Why Choose the ABB 1SAL100573R9901 MC1I301ATD Mini Contactor?
The ABB 1SAL100573R9901, manufacturer model MC1I301ATD, is a compact 3-pole mini contactor designed for switching and controlling electrical loads in residential, commercial and industrial applications. Its space-efficient design provides reliable contactor performance where control-panel space is limited.
The MC1I301ATD features three normally open main contacts together with one normally closed auxiliary contact. Its low-consumption 24 V DC, 1.2 W coil allows the contactor to be controlled directly by suitable PLC outputs, making it particularly useful in automated machinery and industrial control systems.
Rated for 4 kW at 400 V AC-3 with a rated operational current of 9 A at 400 V AC-3, the MC1I301ATD is suitable for controlling three-phase motors and other electrical loads. Its screw terminals and support for rail or wall mounting provide flexible installation within control panels and electrical enclosures.

Compact Motor Control for Industrial Automation
Mini contactors such as the ABB MC1I301ATD provide electrically operated switching of motors and other power loads while occupying less panel space than conventional contactors. The three normally open main contacts allow three-phase loads to be switched simultaneously, while the integrated auxiliary contact can be incorporated into signalling, interlocking and control circuits.
The MC1I301ATD is particularly suitable for automated equipment because its low-consumption 24 V DC coil can be controlled directly by suitable PLC outputs. Its compact dimensions, screw terminals and flexible mounting options make it practical for machine builders and panel designers seeking dependable switching in space-constrained control systems.
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.
