Contactors

Industrial Contactors (Motor Switching Components)

Industrial contactors are used to switch and control electric motors and power circuits in automation panels, MCCs, and OEM machinery. They are a core component in many industrial control systems because they provide reliable on/off control for motor loads while supporting integration with control logic, overload protection, and auxiliary signaling. Contactors are commonly found in applications such as pumps, fans, conveyors, compressors, material handling equipment, and general-purpose industrial machines.

This category includes refurbished contactors used for maintenance replacement and spare inventory. Refurbished motor control components help keep installed equipment running without costly redesign and reduce downtime when a replacement is needed quickly. When selecting a contactor, it’s important to confirm electrical ratings and configuration details to ensure proper fit and reliable operation in your existing system.

What to verify when choosing a contactor

  • Coil voltage and control circuit requirements
  • Line voltage and application voltage
  • Poles and contact configuration
  • Current rating and motor load requirements
  • Auxiliary contacts needed for feedback/interlocks
