Relay Vs Circuit Breaker

Fundamental difference is that relay is a sensing device where as circuit breaker is a fault interrupting equipment.

Relay vs circuit breaker. Circuit breaker breaks the circuit automatically when receives the signal from the relay. The relay does not break the contact. These relays are capable of sensing greater fault currents. Main difference relay vs.

A contactor energizes and de energizes a motor based on information from the motor starter control system. Power overloads and short circuits may cause equipment damage and sometime fire and human casualties. In case of phase to ground faults high currents flow to the grounded neutral of the transformer. Usually the contacts of the earth fault relay are connected to the trip circuit of circuit breakers at the output side of the transformer.

A motor starter energizes and de energizes a motor using a contactor system of contactors or other means. The main difference between relay and circuit breaker is that a relay is typically used as a switch in circuits with small currents whereas a circuit breaker is used to sense and stop large currents from flowing in circuits. Relay vs circuit breaker. Earth fault relay senses these faults.

Its basic function is to interrupt current flow after a fault is detected or after it receives the signal from the relay. A relay is a switch used as sensing and controlling device which makes and closes the contacts electronically or electromechanically. Relay is a device or switch that used to sense any fault in the power system and send the signal to the circuit breaker. Therefore it can be put to use for satisfying requirements only.

The relay is a switching device which gives a signal to the circuit breaker as soon as the fault occurs in the power system. Relays and circuit breakers are devices used to stop currents flowing through circuits. So a relay is a type of sensing and switching device. Whereas the circuit breaker is a device or switch that breaks the signal after the detection of any fault in the system.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Relay is a protective device which senses the faulty conditions in a power system line and initiates the operation of circuit brea. The detailed description of difference between relay and circuit breaker is described below. Main differences between circuit breaker and relay.

Relay is also used as a protective device which sense the fault signal and sends to the circuit breaker which make decision to make or break the circuit based on the provided information by the relay. Electricity is a powerful source of energy and its applications are innumerable.
