Why Choose the ABB 1SAL102158R9901 MC1 Mini Contactor?
The ABB 1SAL102158R9901, designated MC1A301AR6, is a compact and reliable AC-operated mini contactor designed for switching three-phase motors and resistive loads in industrial control systems. As part of the ABB MC1 mini contactor range, it combines three normally open main poles with one normally closed auxiliary contact for control, status monitoring and electrical interlocking.
This mini contactor delivers dependable electromechanical switching while helping machine builders and panel manufacturers conserve valuable enclosure space. Its ring-tongue terminals provide secure electrical connections, making it suitable for industrial equipment and installations exposed to vibration.
With an AC-3 operational current of 9 A at 400 V, a motor rating of 4 kW at 400 V and a 220–230 V AC control voltage, the MC1A301AR6 is suited to compact motor starters, machinery and OEM control assemblies. Its DIN-rail mounting format enables straightforward installation inside electrical panels.

Reliable Switching for Compact Motor-Control Systems
Mini contactors such as the ABB MC1 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 and protection devices must be installed within a limited enclosure.
The MC1 range can be combined with compatible ABB manual motor starters, overload relays and accessories to create coordinated motor-control solutions. The integrated normally closed auxiliary contact supports electrical interlocking, status monitoring and control-sequence functions.
Typical Applications
- Compact motor starters and electrical control panels.
- Industrial machinery and automation equipment.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Heating and resistive-load switching.
- OEM machinery and building-services controls.
