LS Electric Power Contactor – Reliable Circuit Control

LS Electric MC-400A/4 power contactor is a robust solution for frequent switching of electrical circuits, both in industrial and commercial applications. Designed to operate with AC and DC loads, it provides reliable operation and long service life. This device is a key element of automation systems, enabling safe and efficient control of motors, heaters and other energy consumers.

Construction and operating parameters

The MC-400A/4 contactor is characterized by its versatility thanks to a wide range of control coil voltages – from 100 to 240 V AC/DC. The construction with three main poles (3P) and two normally open (NO) and two normally closed (NC) auxiliary contacts – a 2a2b configuration – provides flexibility in control circuit design. The rated current of 400A allows for handling significant loads, and the maximum motor power reaching up to 200kW makes it suitable for demanding applications. Mounting on a DIN rail or directly on a panel facilitates integration with existing infrastructure.
