TECHNICAL DATA TECHNICAL DATA

MNO ac and MNO dc are, basic fourpole contactor relays. With add-onblocks, these contactor relays can giveyou a maximum of 8N0 to 8NC contactcombinations..

MNO ac & MNO dc are available withfollowing contact combinations.

FeaturesFront ON / OFF indication. Suitablefor DIN Rail / Base mounting. Easyaccessibility to coil & contacts.Terminal marking as per EN 50011.

BenefitsAlphanumeric terminal markingseliminate wiring error. Coil voltageindication on coil terminals makeidentification easy. Drilling to actualsize reduces mounting time.

Types MMOO ac and dc are, basic fourpole units. With add-on blocks, thesecontactors can give you as many astwenty-five different contactcombinations from 4N0 to 4N0 +4NC. That means a single MMOOcontactor with four add-onblocks eliminates the need to stockcontactors of various contactcombinations.

Type contact system is indgeniouslydesigned for on - the - spot conversionof 4N0, 4NC, and vice versa, no sparecontacts or springs required

Coil replacementIt is easy. No need for any specialtools. No need to remove theContactor from the panel or disturb thewires. In ac contactors, just slide thetwo arc-shields out, free the contactbridge and detach it. In dc contactors,just remove the two screws and detachthe arc-shield assembly.

Compact &ConvenientSeveral contactors can be mountedside by side, close to each other in acontrol panel. The proximity will notimpair inspection of any of thecomponents - magnets, contactors orcoil - because accessibility is from thefront.

Contact bridge gives a positive 'ON' /'OFF' indication from the front.

Distinction between NO and NCcontacts is clearly visible from thefront. A red dot on the terminalindicates the NC contact.
