DC power contactor LS Electric MC-18b 12VDC 1a1b MC-18B 12VDC 1A1B

DC Contactor for automation and power distribution

This three-pole LS Electric MC-18B power contactor, powered by 12VDC, is a reliable component designed for a wide range of applications in automation and power distribution systems. It will work well in both industrial installations and more demanding commercial applications. The contactor design with integrated 1a1b auxiliary contacts provides flexibility and ease of integration with existing control systems.

Characteristics and application

The MC-18B contactor is characterized by a rated current of 18A in category AC-3, which allows for effective switching of loads up to 7.5kW. The 12VDC coil voltage makes it an ideal solution for systems powered by DC voltage. The configuration of normally open (NO) and normally closed (NC) auxiliary contacts enables the implementation of various control and signaling functions. Mounting on a DIN rail or panel ensures convenient installation and adaptation to different environmental conditions.

Advantages and benefits
