What is an auxiliary contact on a breaker?

Auxiliary contacts monitor Eaton circuit breakers and provide a signal to outside equipment when the breaker trips. In the event of an overcurrent or short circuit, these contacts and switches keep workers and equipment safe by sounding an alarm, initiating a shutdown, or starting up a backup power source.

What is the uses of auxiliary contact in a contactor?

The auxiliary contact is often used in a relay logic circuit, or for some other part of the motor control scheme, typically switching 120 Volt AC power instead of the motor voltage. One contactor may have several auxiliary contacts, either normally-open or normally-closed if required.

What is the difference between a magnetic contactor and relay?

A contactor joins 2 poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. Additionally, contactors are commonly rated for up to 1000V, while relays are usually rated to only 250V.

What is the main contact?

noun. Any of the contacts of a switch which actually control the flow of current in an electric circuit.

When compared to the main contacts auxiliary contacts carry?

Main contacts are designed to carry high voltage and high current whereas auxiliary contacts are designed for low voltage and low current only. 4.

What is main contactor?

A contactor is one of the main electrical circuit parts, which can stand on its own power control device or a part of a starter. They are used to connect and break power supply lines running through power lines or repeatedly establish and interrupt electrical power circuits.

What is the main function of contactor?

A contactor is an electrical device which is used for switching an electrical circuit on or off. It is considered to be a special type of relay.

What is different between contactor and relay?

Control Relay: It is a device through which contacts in one circuit are operated by an alteration in conditions in the same circuit or in associated circuits. Contactor: It is a device which is used for repeatedly establishing and interrupting an electric circuit under normal conditions.
