Product details
Auxiliary contacts are additional contacts, physically linked to primary switching equipment like contactors, circuit breakers, or relays, that provide secondary switching functions. They essentially act as support devices, typically used to control or monitor the operation of the main switching equipment. Main contacts are designed to carry high voltage and high current whereas auxiliary contacts are designed for low voltage and low current only. Auxiliary contacts serve several purposes for motor-operated devices and electrical professionals regarding safety and protection against electrical faults.
