©Switches through 1200 Amps listed by Underwriters'Laboratories for use on circuits delivering up to200,000 Amps RMS symmetrical fault current, providedclass "R", "J", "L", or "T" fuses are used. Rejection kitsmust be installed for "R" fuse applications.

©Class "L" fuse provision. Single fuse per pole. Suppliedwithout knockouts.

Discount Schedule "S"

©Order 3 pole switch from chart above, and neutral fromaccessory page.

©Starting current of motors above standard horsepowerrating may require use of time delay fuses.

©For service equipment or applications requiring a solidneutral, order neutral kit as an accessory, page SS-11.

©Availability to be announced.©400A and larger Type 3R switches have no provisions for

mounting hubs. Drill or punch hole in the field toaccommodate hub size desired.

©60-200A switches are also rated 600V DC.

SAFETY SWITCHESTECHNICAL INFORMATION ss 3

General Duty Switches; Prefix "G"General duty switches are available in indoorTYPE 1 and outdoor TYPE 3R enclosures.Enclosures can be locked closed and operatinghandles can be locked "OFF". Series "G"switches have a quick-make, quick-breakmechanism. Fusible switches are available in1 pole S/N, 2 pole S/N and 3 pole S/Nconfigurations. Non-fusible switches areavailable in 2 pole and 3 pole configurations.General duty switches are limited to 240V AC,600 Amps max. rating.All 30 Amp compact fusible and non-fusible"G" prefix switches are rated 10,000 Ampmaximum withstand.

All 30-600 Amp "GF" and "GU" prefixswitches are suitable for use on systemscapable of delivering not more than 100,000RMS symmetrical Amps of fault current withClass "R" fuses and the appropriate adapterkit installed. These 100-600 Amp "G" prefixswitches may also be used on systems capableof delivering not more than 100,000 RMSsymmetrical Amps of fault current with "T"fuses and the appropriate adapter kit installed.In addition, 200-600 general duty switchesmay also be used with J fuses on systemsnot capable of delivering more than 100,000RMS symmetrical amperes of fault current.General duty switches are UL Listed for useas service equipment and are horsepowerrated for use with motor loads.

General duty enclosed switches are used forlight duty applications where loading andswitching operations are not excessive.

Heavy Duty Switches, SingleThrow; Prefix "H"Heavy duty switches are available in indoorTYPE 1, outdoor TYPE 3R, Watertight Type4/4X, and industrial TYPE 12 enclosures. Dualcover interlocks are provided, such that thedoor cannot be opened with the switch "ON"and the switch cannot be turned "ON" withthe door open. A defeat mechanism allowsservicing by authorized personnel. Handlesmay be locked "OFF" with up to 3 padlocks,and doors may be padlocked closed.Mechanism is "TEASE-PROOF" quick-make,quick-break. Fusible switches are available in 2pole S/N, 3 pole and 3 pole S/N. Non-fusibleswitches are available in 3 pole.Suitable for use on systems capable ofdelivering not more than 200,000 RMSsymmetrical amperes of fault current whenClass "J" or "R" fuses are installed except the800 and 1200A switches, which are suitablefor use on circuits capable of delivering notmore than 200,000 RMS symmetrical amperes

of fault current when Class "L" fuses areinstalled. 100-1200A switches with Class "T"fuses and field adapter kit 200,000 RMSsymmetrical rated.Heavy duty switches are dual horsepowerrated and are listed by UL for use as serviceentrance equipment.Heavy duty switches are intended forapplications where rugged construction,reliable performance, continuity of serviceand ease of maintenance are required.

Protector-Lock® Switches;Prefix "H"The Murray Protector-Lock" switch isdesigned to eliminate shock hazard due todisconnecting heavy duty portable electricalequipment under load. When the switch is inthe "ON" position, the safety bar blocks theself-contained receptacle and preventsinsertion or removal of the plug. When theswitch is "OFF", the bar retracts, allowinginsertion or removal of the plug.Protector-Lock8 switches consist of aheavy duty, 30 or 60 Amp, 600V AC, 3 polefusible or non-fusible enclosed switch, andeither Grouse-Hinds® or Arrow Hart®Industrial receptacles.Applications include industrial plants whereportable conveyors and welders are used, andtruck terminals where on-board refrigerationunits require stand-by power.

Double Throw Switches;Prefix "HD"Double throw switches are available in TYPE 1and TYPE 3R enclosures. Covers are dualinterlocked with the operating mechanismsuch that the cover cannot be opened whenthe switch is in either "ON" position, and theswitch handle cannot be moved to either"ON" position if the cover is open. Handlemay be padlocked in the "OFF" position.Switching action is quick-make, quick-break inboth "ON" positions.They are available in 30-600 Amp ratings,240V AC, fusible and non-fusible, two andthree pole.Double throw switches are usually applied astransfer switches to switch a load from onepower source to another, but can be fieldconverted to switch one power sourcebetween two loads. Switching mechanism islocated on line side of fuses allowing for asafer fuse replacement.

Pullout Switches; Prefix "P"Pullout switches are intended for outdoordisconnect applications, primarily asair-conditioning disconnects. They are housedin TYPE 3R enclosures, with covers which maybe padlocked closed. Pullout heads arecompletely removable for safety whenservicing rotating equipment. They areavailable in fusible (Class "H") and non-fusiblemodels, single phase, 120/240VAC, 30 and60 Amps. Withstand ratings of standard "PE"prefix models is 10,000 Amps RMS Sym.
