Why Choose the ABB 1SAL102382R9902 MC2 Mini Contactor?
The ABB 1SAL102382R9902, designated MC2C301ATWJ, is a compact and reliable DC-operated mini contactor designed for switching three-phase motors and resistive loads in industrial control systems. As part of the ABB MC2 mini contactor range, it combines three normally open main poles with one normally closed auxiliary contact for monitoring, control and electrical interlocking.
This mini contactor features a low-consumption DC coil with an extended operating-voltage range, supporting dependable integration into automation equipment and electronically controlled machinery. Screw terminals provide straightforward wiring, while its compact enclosure helps reduce the panel space required for motor-control components.
With an AC-3 operational current of 12 A at 400 V, a motor rating of 5.5 kW at 400 V and a 110 V DC control voltage with ±30% tolerance, the MC2C301ATWJ is suitable for compact motor starters and demanding OEM control assemblies. Its DIN-rail mounting format enables efficient installation inside electrical panels.
