Contactors

Contactors are electrically controlled switching devices used for switching an electrical power circuit, similar to a relay but with higher current ratings. They are essential for controlling electric motors, lighting, heating, capacitor banks, and other electrical loads in industrial and commercial applications.

Designed for frequent switching operations, contactors offer high reliability and long mechanical life. They are built with arc suppression features, auxiliary contacts, and compact modular construction to support seamless integration into control panels and automation systems.

Benefits With Our Contactors

Efficient and dependable control for motors and high-load electrical circuits.

  • Durable design for high-frequency operations
  • Integrated auxiliary contacts for automation control
  • Coil options for AC and DC voltages

Our contactors comply with IEC 60947-4-1 and are available in a wide range of current ratings, from fractional horsepower to heavy industrial loads. They support both 3-pole and 4-pole configurations and are suitable for direct-on-line (DOL) and star-delta starter applications. Their modular accessories include timers, mechanical interlocks, and surge suppressors.

Most Common Questions

Why use a contactor instead of a relay? Contactors are specifically designed for high-power applications and frequent switching. They provide arc suppression and better heat dissipation, making them ideal for motor control and industrial loads.

Contactors are primarily used to control electric motors, lighting, heating, capacitor banks, and other heavy electrical loads. They are ideal for applications requiring frequent switching in industrial automation and power control systems.
While both devices perform switching functions, contactors are designed for higher current capacities and frequent operation. Relays are used for control signals and smaller loads, whereas contactors are built for motor control and power switching.
Contactors come in various types including AC contactors, DC contactors, and specialty contactors for lighting or capacitor switching. They are available in 3-pole, 4-pole, and mini versions with a range of auxiliary contact configurations.
Regular maintenance includes inspecting the contact surfaces for wear, ensuring coil voltage is stable, and checking the mechanical operation for smooth switching. Contactors in heavy-duty or high-cycle applications should be inspected more frequently.
