Why Choose the ABB 1SAL102176R9902 MC2 Mini Contactor?
The ABB 1SAL102176R9902, designated MC2A310AR7, is a compact AC-operated mini contactor designed for reliable switching of 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 open auxiliary contact in a space-efficient enclosure.
This mini contactor provides dependable electromechanical switching for machinery, control panels and building-service equipment. Its integrated auxiliary contact supports signalling, interlocking and control-circuit functions, while ring-tongue terminals provide secure electrical connections in applications where vibration resistance is important.
With an AC-3 operational current of 12 A at 400 V and a motor rating of 5.5 kW at 400 V, the MC2A310AR7 is suitable for compact motor-control assemblies. Its narrow format and DIN-rail mounting simplify installation in space-constrained electrical panels.

Reliable Switching for Compact Motor-Control Systems
Mini contactors such as the ABB MC2 provide electrically controlled switching of motors and resistive loads while occupying less panel space than conventional contactors. Their compact construction makes them particularly useful in machinery where several switching devices must be installed within a limited enclosure.
The MC2 series supports coordinated motor-control solutions with compatible ABB manual motor starters, overload relays and accessories. Its robust contact system, integrated auxiliary contact and secure terminal arrangement make it suitable for frequent switching duties in industrial and commercial equipment.
Typical Applications
- Compact motor starters and control panels.
- Industrial machinery and automation equipment.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Heating and resistive-load switching.
- Building-services and OEM control assemblies.
