Control Contactors

Control contactors switch power to motors, heaters, lighting and other loads on command from a control circuit. They're a core part of industrial control panels, letting low-voltage signals from PLCs and pushbuttons safely switch high-current loads.

Contactor Types

• IEC contactors – compact, application-rated designs
• NEMA contactors – size-rated for robust industrial use
• Definite purpose contactors – HVAC and refrigeration equipment
• Reversing contactors – forward/reverse motor control
• Accessories – auxiliary contacts, suppressors and overloads

Choosing a Contactor

Size to the load's current and utilization category, such as AC-3 for motors, along with voltage, coil voltage and the number of poles. For frequent switching, check the electrical life rating. Pair with an overload relay to build a motor starter.
