They are used in two completely different ways in the System. starter relays for example ,uses a low current to pull core and close high current contacts needed for straiting only, or blower motor Relay's Circuit breaker can protect entire systems in your whole house , if one phase over loaded they are mechanically set up so that both phases will trip. on auto's they are used as switches to close the two heavier gauge wire for the load. fusible links in auto's are made to protect entire systems. note: in homes circuit breakers can also protect individual circuits. Not only the whole house (MAIN BREAKER).

Parking lights will not turn off is it a relay or circuit breaker?
It is a relay or switch problem. A circuit breaker or fuse won't keep a light on.
What is Trip circuit supervision?
Trip circuit supervision is defined as the protection equipment which monitors the continuity of the trip circuits of a circuit-breaker. The trip circuit supervision relay will monitor the proper functioning of trip circuits.
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
What is used in an electrical circuit to prevent a short current?
A Fuse or a circuit breaker can be used to protect an electric circuit from over loads. A surge arrestor / over voltage relay can be provided for voltage protection An ELCB/ Earth fault Relay may be provided for earth fault protection. Electrix Chennai, India.
A circuit protection device that opens when overloaded and then automatically resets is known as a?
If it is on a motor, it is called a self or auto resetting IEC thermal overload protection device. If it is on anything else, it is a bad idea.
What is 50G protection relay mean?
50 is the ANSI device number for an instantaneous overcurrent relay. The G suffix stands for "ground." A 50G protection relay trips the circuit breaker without time delay when it detects a ground fault on the circuit.
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.

What is LBB protection Relay?
LBB is local breaker protection
What is Trip circuit supervision?
Trip circuit supervision is defined as the protection equipment which monitors the continuity of the trip circuits of a circuit-breaker. The trip circuit supervision relay will monitor the proper functioning of trip circuits.
What is inter trip relay?
A protection signalling system whereby a signal initiated at one station trips a circuit-breaker at another station.
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
What is the use of over voltage relay?
The use of over load relays in circuits is to protect the circuit against over heating .
What do relay and circuit breakers use?
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
Where is the motor relay circuit breaker located on a 1989 mustang?
The motor relay circuit breaker may be found on the driver's side of the vehicle, on or near the fender apron. There is a cable that runs from it to the battery.
