Why Choose the ABB 1SAL102615R9901 MC1 Mini Contactor?
The ABB 1SAL102615R9901, designated MC1A310ATW, 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 open auxiliary contact for signalling, control and electrical interlocking.
This mini contactor delivers dependable electromechanical switching while helping machine builders and panel manufacturers conserve valuable enclosure space. Screw terminals simplify wiring and maintenance, while the integrated auxiliary contact supports control feedback and holding-circuit functions.
With an AC-3 operational current of 9 A at 400 V, a motor rating of 4 kW at 400 V and an AC coil rated for 500 V at 50 Hz or 600 V at 60 Hz, the MC1A310ATW is suitable for compact motor starters and machinery using higher-voltage control supplies.

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 useful in machinery where multiple 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. Its integrated normally open auxiliary contact supports status signalling, seal-in circuits and automated control sequences.
Typical Applications
- Compact motor starters and electrical control panels.
- Industrial machinery with high-voltage control circuits.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Heating and resistive-load switching.
- OEM machinery and automation assemblies.
