Why Choose the ABB 1SAL102174R9901 Mini Contactor?
The ABB 1SAL102174R9901, manufacturer model MC1AB00AR7, is a compact and reliable four-pole mini contactor designed for switching electrical loads in industrial machinery, commercial equipment and automation systems. As part of the ABB MC1 mini contactor series, it delivers dependable performance where control-panel space is limited.
This mini contactor provides two normally open and two normally closed main contacts, allowing flexible control of power and signalling circuits. Its ring-tongue terminals support secure conductor connections, while the compact housing is suitable for installation within electrical control panels.
With a conventional free-air thermal current of 20 A, an AC-3 operational current rating of 9 A at 400 V and an AC-3 motor rating of 4 kW at 400 V, the MC1AB00AR7 is suitable for controlling motors and other industrial electrical loads.

Reliable Load Control for Industrial Machinery
Mini contactors such as the ABB MC1AB00AR7 use an electromagnetic coil to switch their main contacts remotely. This allows motors and other electrical loads to be controlled through pushbuttons, relays, programmable controllers and automated machine-control circuits.
The combination of normally open and normally closed main contacts supports flexible switching and interlocking arrangements. Its compact dimensions and durable mechanism make the contactor suitable for new machinery, control-panel construction and replacement applications.
Typical Applications
- Industrial motor-control circuits.
- Pumps, fans and ventilation equipment.
- Heating and lighting load switching.
- Packaging and production machinery.
- Commercial building-control systems.
- Automation panels and OEM equipment.
