 What is the difference between Relay and Circuit Breaker?
• The relay is used for controlling a circuit with isolation between control circuit and the controlled circuit. Circuit breaker is used for disconnecting or isolating a circuit from the power source or a higher level circuit.
• The relay operates on a low power voltage input while circuit breakers are automatic on-load devices.
• Circuit breakers are used one per circuit while relays can be used to control/select one among many connected to it.
• A relay may be included in a circuit breaker, but not the other way around.
• A relay can also be considered as an electrical amplifier for discrete signals.
