SS90910 Lauritz Knudsen Contactor ML 4 (3 Pole, 70A AC-3) - 2 NO + 2 NC

The Lauritz Knudsen SS90910 is a 3-pole power contactor rated 70A in AC-3 and 100A in AC-1. It has 2 NO + 2 NC auxiliary contacts. It is used for motor switching and power control.

The Lauritz Knudsen SS90910 suits motor circuits up to 70A in AC-3 duty. It can be combined with a matching overload relay and auxiliary contact blocks to build DOL, star-delta and reversing starters from one product family.

This contactor is commonly used in DOL motor starters, star-delta starters, reversing starters, pump and compressor panels, HVAC control panels, conveyor controls and general power switching in automation panels.

Pair the contactor with a Lauritz Knudsen overload relay whose adjustable range covers your motor's full load current (0.58 × full load current when the relay sits in the winding circuit of a star-delta starter). Common accessories are auxiliary contact blocks, mechanical interlocks for reversing starters, surge suppressors for the coil, and timers for star-delta starters. Check the Lauritz Knudsen catalogue for the accessory part numbers that fit the SS90910.

Select a coil whose voltage and type — AC (50Hz) or DC — match your control circuit supply, for example 24V DC for PLC-driven panels, 110V AC where a control transformer is used, or 230V / 415V AC for mains-derived control. Standard coil voltages for the SS90910 are 110V / 240V / 415V, 50Hz, and the coil suffix is specified while ordering.
