DC power contactor LS Electric MC-18b 220VDC 1a1b MC-18B 220VDC 1A1B

LS Electric MC-18B power contactor is a robust component designed for reliable switching of direct current circuits. It is a three-pole device suitable for industrial automation, control systems, and power supplies. The contactor's construction is based on proven technology, guaranteeing long life and high resistance to working conditions.

Characteristics and application

This model, designated MC-18B 220VDC 1a1b, operates at a coil voltage of 220V DC and allows for the safe switching of loads up to 18A. It has a standard auxiliary contact configuration – one normally open contact (1a) and one normally closed contact (1b), which simplifies integration with various control systems. This contactor is particularly useful in applications requiring frequent switching of DC loads, such as electric drives, solenoids, or switch-mode power supplies. Mounting is done on a DIN rail or directly on the panel using screws.
