Contactors - FAQs

What are contactors and how are they used in motor control systems?

Contactors are electrically operated switches designed to control high-power circuits, commonly used in motor control systems for electric motors, lighting, HVAC, and industrial equipment. Electrical contactors, including low voltage contactors and capacitor switching contactors, are essential for automation, allowing remote switching and control.

What is a contactor in motor control systems?

A contactor is an electrically controlled switch used for switching a power circuit, primarily in motor control systems. Unlike a relay, it is built to handle higher currents typical of electric motors and industrial loads.

When should I use an ABB safety contactor?

Use an ABB safety contactor when fail-safe disconnection of power is required, such as in emergency stop circuits. These safety contactors comply with safety standards for functional safety and can be integrated into machine shutdown systems. View the range of ABB Safety Contactors here.

What are general-purpose contactors and where are they used?

General-purpose contactors are versatile devices for controlling resistive, inductive, and motor loads across industrial and commercial systems. Applications include lighting, pumps, fans, and compressors, with models supporting both single phase motor contactors and 3 phase contactors.
