Why Choose the ABB 1SAL102170R9901 MC1AA00ARJ Mini Contactor?
The ABB 1SAL102170R9901, type MC1AA00ARJ, is a compact and reliable four-pole AC-operated mini contactor designed for switching motors and resistive loads in industrial control systems. As part of the ABB M mini contactor series, it offers dependable switching performance within a space-efficient enclosure.
This contactor incorporates four normally closed main contacts and uses dedicated screw terminals for secure connection of conductors fitted with ring-tongue terminals. Its compact construction and DIN rail compatibility simplify integration into machinery, control panels and industrial automation equipment.
With an IEC AC-3 motor rating of 4 kW at 400 V, an AC-1 operational current rating of 20 A at 400 V and an AC control coil rated for 110–115 V at 50 Hz or 110–120 V at 60 Hz, the MC1AA00ARJ provides a practical switching solution for demanding control applications.

Compact Switching for Industrial Control Systems
Mini contactors such as the ABB MC1AA00ARJ use an electrically energised coil to operate power contacts within machinery and automation circuits. The four normally closed poles open when the coil is energised, making this configuration suitable for isolation, interlocking and specialised load-control functions.
The ABB M series is designed to provide high switching performance in limited installation space. Its durable mechanism, secure ring-tongue connections and compatibility with standard DIN rails support reliable operation in industrial panels and OEM equipment.
Typical Applications
- Industrial machinery control circuits.
- Electrical interlocking and isolation functions.
- Motor and resistive-load switching.
- Automation panels and distribution equipment.
- Applications exposed to vibration or mechanical movement.
- OEM equipment and machine-building projects.
