ADXC soft startersADXC soft starters have a45mm wide casing. They canbe installed either on 35mmDIN rail or fixed on amounting plate, by scews, aresuitable for soft start andstop, by current limitation, ofthree-phase asynchronousmotors rated up to 45A.Alarms are available, acrossthe range, for overcurrent,over temperature and overvoltage conditions. The 600Vversion is also equipped withtwo relay outputs for remotesignalling of alarms andbypass relay closing.

Spring-clampterminal contact andLED elements

LOVATO Electric addnew spring-clampterminal types to theexisting screw andfaston terminalcontact and LED

elements, all to be mountedon the LPXAU120 adapter. This type of push-inconnecting technology is timesaving during wiring since itis a tool-less operation.

Auto-monitor contactelements

These particular NCcontacts, used withnon-illuminated latchemergency stoppushbuttons, providefor constant monitoring

of exact mounting andoperation of the NC contacts.Once the contacts areinstalled on the mountingadapter in a correct way andwith a correct running of theequipment, they work asnormal NC contacts.Their trait is to break tonormally-open state and, inso doing, isolate the circuitwhen malfunctions takeplace, for instance after thecontact detaches from theadapter or if these two comeloose from the pushbuttonitself, due to strong vibrationsor shock of some sort.

Control stations andbase-mount contactand LED elements

LOVATO Electricrelease the newinsulatedpolycarbonate LPZcontrol stationsfeaturing modern

design and aesthetics in linewithpushbuttons and selectorswitches.The types include emptystations, with 1 to 6 holes,having excellent protectiondegrees per IEC IP66, 67,69K and UL Type 4/4X. Theextreme sturdiness allowsuse in every type ofapplication. To ease wiringinside the new LPZpushbutton stations,dedicated contact and LEDelements have been made todirectly fit onto the controlstation base. This sort ofinstallation provides for allwiring to be entirely withinthe base. As a result, coveropening and fixing are safe,quick and simple operations.

IP65 enclosed switchdisconnectors

LOVATO Electric havecompleted the line ofenclosed switchdisconnectors by introducinga new enclosure frame size inbetween the two availableGAZ1 and GAZ3 types. Thenew GAZ2 version is availableempty or already completewith either a three or four-pole switch disconnector,rated 63A, 80A or 100A inIEC AC21A duty. The IP65protection degree allowsthem to be installed in severeambient conditions. This product range has beenextended to include newchangeover switches, in boththree and four-pole versions,rated 25A to 125A in IECAC21A duty, housed ininsulated enclosures.

Fuse holders 10x38size

The range is composed of:one-pole, one-pole with lightindicator, one-pole + neutral,two-pole, three-pole andthree-pole + neutral versions.Using the availableaccessories, multi-pole typescan be assembled startingfrom the single-pole device.In addition, there is aninsertable label to identifyeach single pole. ULcertifications, as Listed orRecognized (cULus or cURus)for USA and Canadadepending on type, have nowbeen obtained for all10x38mm fuse holders, bothAC and photovoltaic DCversions.

Miniature andresidual circuitbreakers

LOVATO Electric include in itsproduct offering new modulardevices dedicated to protectpeople and installations. Theyare miniature circuit breakers(MCBs) up to 125A andresidual current circuitbreakers (both RCBOs andRCCBs). The MCBs have a highbreaking capacity of 10kAand most are certified by ULfor USA and Canada assupplementary protectors perUL 1077.

Surge protectiondevices

LOVATO Electric release twonew types of surge protectiondevices for photovoltaicapplications, compliant withthe new EN 50539-11standard. The new products, availablewith removable plug-incartridges, are used ininstallations with voltage upto 1200VDC. By using theircontact remote feature,indication of the device statuscan be remoted so as tosignal when replacement isneeded. The new SPDs havehigh Iscpv short-circuitcurrent rating up to 1000A.This current value is veryimportant because itindicates the maximumcurrent which their thermaldisconnector is capable ofisolating.

Interface protectionPMVF 51

The PMVF 51 interfaceprotection gives all thefunctions and controlsrequired by the Italian CEI 0-21 standard (June 2012edition and subsequentrevisions) regarding low-voltage connection of micro-generation systems, such assolar or wind installations,between the energygeneration system and thenational power grid. Inaddition to compulsoryvoltage and frequencycontrols, when currenttransformers are connectedwith the PMVF51 interfaceprotection, it can also put atdisposal current and energymeasurements as well asunbalanced power controlwith the optional dedicatedexpansion module installed.

New design for the direct operating and door-couplinghandles introduced for GE switch disconnectors - 160 to 1600A ratings.OFF and ON positions are clearly and preciselyidentifiable.

New GE series handles

Micro PLC with built-in RS485

LRD20R D024 P1is a new version ofthe Micro PLCs,featuring integratedRS485 serialinterface, whichprovides for simple

automated functionintegration, typical of the LRDseries with supervision andcontrol software.Transducers, field and usercommands can all be easilyelaborated by the Micro PLCto program its outputs.

Automatic batterychargers BCG

The new BGC battery chargerseries introduces switchingtechnology even for the 12A12VDC and 10A 24VDCratings of lead-acid batteryapplications. Two voltagelevels can be selected,suitable for different sorts ofbattery and maximumcharging current can beadjusted. The batterychargers are enhanced byautomatic protections andindication LEDs for alarmand battery operatingconditions. The relay output isautomatically activatedwhenever a malfunction ofthe system takes place.

Digital multimetersDMG 600 - DMG 610(96x96mm)

DMG6 digital multimeters,for single or three-phasesystems, permit to viewelectrical quantities of theinstallation on their backlightLCD screen and, by installingone of the EXP seriescommunication modules(USB, RS232, RS485,Ethernet), thesemeasurements can beaccessible to the supervisionsoftware via appropriateprotocol. The DMG 610 type is alreadyequipped with built-in RS485interface. Data collection canbe done directly on themultimeter front as well, byconnecting the CX01 or CX02dongle to its optical port,without having to open theelectrical panel.

DME energy metersFour new models completethe existing range: DME D115 T1 (40A singlephase, 2-module type)improves legibility ofinstallation energy and powermeasurements by users,DME D130 (63A singlephase) is expandable withEXP series modules (e.g. forload supervision); while DME D121 (63A singlephase) and DME D320 (CT/5A three phase) have a built-in RS485 communication portmaking these two directlyintegrable in supervisionsystems. Therefore, acquired data ofthe energy meters can becentralised and thendeveloped with softwareelaboration.

Data concentratorDME CDPV1 forphotovoltaicmonitoring

DME CDPV1 is a devicespecifically for monitoringphotovoltaic installations. Byconnecting at least two singleor three-phase DMED energymeters to the data concentratorin an installation, the user canobtain energy produced by thePV installation, energy drawnby loads and ultimately, energyexchanged (import and export)with the energy provider.DME CDPV1 is already dulyprogrammed to automaticallycalculate the percentages ofproduced (total and partial) andconsumed apparent power,average power values and theoperating status of the AC/DCinverter (if it is equipped withany digital outputs).It is customisable by the userby setting up additional valuesto control the installationefficiency. In addition, with theEXM series expansion modules,DME CDPV1 can also be usedto supervise loads according tologic functions, defined by theuser and based on the energyavailability. By adding anEthernet communication port inaddition to the RS485 alreadybuilt in, remote control andsupervision can be done by the

software..

Motor protection circuit breakersWith thermal and magnetic trip releases

1General characteristicsThe SM1 is a modern series of circuit breakers withthermal and magnetic trip releases and high breakingcapacity. Motor control and protection, up to 15kW at400V/20HP 480V/30HP 600V, are possible by choosingthe suitable adjustment range, 0.1 to 32A.A magnetic trip indicator integrated on the SM1 breakersavoids dangerous closing operations during short-circuitconditions, previously disconnected by the breaker.The SM1 types are suitable for isolation according toIEC/EN 60947 standards. Their high breaking capacity consents to excludeprotection fuses on the majority of the installations.

SPD COORDINATIONIn order to obtain an effective protection against overvoltage, it is advisable to install several SPDs coordinated with one another in cascade connection. For instance, it is advisable to have a Type 1 SPD in the main distribution board,a Type 2 SPD in the sub-distribution board and a Type 3 SPD near the terminalequipment to be protected. In this way, the energy originating from an overvoltage gradually decreases as itreaches the equipment to protect.

DEFINITIONS AND RATINGSMaximum continuous voltage Uc: Maximum value of AC or DC voltage that the SPD is capable of permanentlywithstanding without activating or getting damaged; this is its rated voltage.

Protection level voltage Up: Maximum value of the voltage between the terminals of the SPD in presence ofan impulsive overvoltage. It is a fundamental parameter to correctly choose theSPD; it must be taken into account with regards to the impulse voltage of theequipment to protect.

Impulse current Imp:Crest value of the current that circulates in the SPD with a 10/350s waveform(activation must be guaranteed for 20 times without damage). It is used to classifySPDs in test class I.

Rated discharge current In:Crest value of the current that circulates in the SPD with an (/20s waveform(activation must be guaranteed for 20 times without damage). It is used to classifySPDs in test class II.

Open circuit discharge voltage Uoc:Crest value of the no-load discharge
