AC power contactor LS Electric MC-18b 400VAC 1a1b MC-18B 400VAC 1A1B

AC power contactor – reliability in automation and energy distribution

LS Electric MC-18B power contactor is a component that will find application in a wide range of automation systems and energy distribution systems. Designed for reliability and durability, it provides a solid foundation for effective control of electrical circuits.

This model, designated MC-18B 400VAC 1a1b, is characterized by its versatility and ease of integration with various systems. Thanks to the standard equipment with 1a1b auxiliary contacts, it provides flexibility in the configuration of control circuits. It is worth noting that for larger models (from 185A) retractable electronic AC/DC coils are available, which further expands the possibilities of application.

The contactor's construction is based on proven solutions, which translates into a long service life – up to 15 million mechanical cycles and 2.5 million electrical cycles. Installation is simple and convenient thanks to the possibility of using both screws and 35mm DIN rail. The four-terminal design facilitates the connection of power supply and load. Standardized dimensions allow for trouble-free replacement of existing contactors from other manufacturers.

Additional features worth noting:

• Wide range of coil voltages: Available versions with AC coils with voltages of 24V, 110V, 220V, 380V and 440V. This allows you to adapt the contactor to specific installation requirements.
• Solid connections: The use of screw terminals ensures secure and durable connection of wires.
• IP20 protection class: This means protection against accidental contact with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted in enclosures.
• Three-pole main contact arrangement: Provides effective switching of three-phase loads.
• Expandability: Availability of modules for capacitor switching and a full range of accessories allows you to adapt the contactor to specific application needs.
