Why Choose the ABB 1SAL100577R9901 MC1K301ATD Mini Contactor?
The ABB 1SAL100577R9901, manufacturer model MC1K301ATD, is a compact 3-pole mini contactor designed for reliable switching of motors and other electrical loads where control-panel space is limited. As part of the ABB M mini contactor range, it combines compact dimensions with a low-consumption DC coil for residential, commercial and industrial control applications.
The MC1K301ATD features three normally open main contacts together with one normally closed auxiliary contact. Its 24 V DC, 2 W coil provides efficient DC operation and can be directly controlled by a suitable PLC, making the contactor particularly useful in automated machinery and industrial control systems.
With a rated operational power of 4 kW at 400 V AC-3 and a rated operational current of 9 A at 400 V AC-3, the MC1K301ATD is suitable for controlling three-phase motors and other electrical loads. Its compact 48 × 45 × 68 mm housing, screw terminals and support for rail or wall mounting provide straightforward integration into electrical control systems.

Compact Motor Control for Industrial Automation
Mini contactors such as the ABB MC1K301ATD provide electrically operated switching of motors and other power loads while occupying less panel space than conventional contactors. The three normally open main contacts enable three-phase loads to be switched simultaneously, while the integrated normally closed auxiliary contact can be incorporated into signalling, interlocking and control circuits.
The MC1K301ATD combines a low-consumption 24 V DC coil with compact dimensions and screw-terminal connections. Its coil allows direct control by a suitable PLC, while its 4 kW AC-3 rating at 400 V makes it a practical solution for machine builders, panel builders and automation engineers requiring compact motor switching.
Typical Applications
- Three-phase motor control.
- Industrial machinery and automation systems.
- PLC-controlled switching circuits.
- Pumps, fans and ventilation equipment.
- Conveyors and material handling systems.
- Residential, commercial and industrial electrical control panels.
