AC power contactor LS Electric MC-500a 400VAC 2a2b MC-500A 400VAC 2A2B

LS Electric MC-500A power contactor – reliable circuit control

The LS Electric MC-500A contactor is a robust solution for frequent switching of electrical circuits, used in industrial automation and power distribution boards. Designed to work with high-current loads, it ensures safe and efficient operation of installations. This model is characterized by high reliability and durability, which translates to a long service life and minimal operating costs.

Construction and application

The MC-500A contactor is an electromechanical device that, when voltage is applied to the coil, causes the main circuit contacts to close or open. The contactor design with three poles (3-pole) allows for controlling three-phase motors. It is standardly equipped with 2a2b auxiliary contacts (two normally open and two normally closed), enabling the implementation of control and signaling functions. A wide range of coil voltages allows it to be adapted to different control systems. It is a key element in power supply systems for machines and equipment requiring frequent starting and stopping, such as pumps, fans, and conveyors.

Key features and benefits

• High rated current: 500A current in AC-3 category allows handling loads with significant power – up to 265kW. This makes the contactor ideal for use in heavy industry.
• Universal coil voltage: Availability of versions with 400VAC or 230VAC/VDC coil allows for flexibility when selecting for an existing electrical installation.
• Standard auxiliary contacts: Built-in 2a2b auxiliary contacts simplify the control circuit design, eliminating the need for additional components.
