Why Choose the ABB 1SAL102164R9901 MC1A400AR6 Mini Contactor?
The ABB 1SAL102164R9901 (MC1A400AR6) is a compact and reliable four-pole mini contactor designed for switching single-phase and three-phase electrical loads in industrial, commercial and building automation applications. As part of the ABB MC1A mini contactor series, it combines strong electrical performance with space-saving dimensions for control panels and machinery where installation space is limited.
The MC1A400AR6 features 4 normally open (NO) main contacts and an AC-operated electromagnetic coil. Special screw terminals are provided for connection using ring tongue terminals, making the contactor suitable for applications where secure terminated conductor connections are required. Compatible front-mounted and side-mounted auxiliary contact blocks can also be added to expand signalling and interlocking functionality.
With a 220–230 V AC 50/60 Hz control supply, a rated operational current of 9 A in AC-3 duty at 400 V and a motor switching capacity of 4 kW at 400 V, the MC1A400AR6 provides dependable switching for compact motor control applications. It also handles up to 20 A in AC-1 duty at operating voltages up to 690 V AC.

Compact and Reliable Switching for Control Systems
Mini contactors such as the ABB MC1A400AR6 use an electromagnetic coil to operate their main contacts, allowing motors and other electrical loads to be switched from a separate control circuit. Their compact dimensions make them particularly useful in machinery, building controls and industrial panels where conventional contactors would occupy unnecessary installation space.
The MC1A400AR6 combines four normally open main contacts with a 220–230 V AC coil and industrial switching ratings of up to 9 A in AC-3 duty and 20 A in AC-1 duty. Its ring tongue connection system, flexible mounting options and compatibility with additional auxiliary contacts make it a versatile switching component for machine builders, panel builders and automation engineers.
Typical Applications
- Industrial motor starters and control panels.
- Single-phase and three-phase load switching.
- Small motor control and starter assemblies.
- Heating, ventilation and HVAC equipment.
- Building automation and commercial electrical systems.
- OEM machinery and compact production equipment.
