An Earth Relay Circuit Brearker(ERCB is a circuit breaker that senses an earth leak within the system and responds by cutting the power to the appliance or section or giving an alarm pending on the complexity of the system.
Most of them can be set to a certain sensitivity, for homes it will be normally 30 mA fixed earth leakage current with an instantanous cut out.
For industrial and commercial application the setting can vary pending on the protection needed.

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 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.
Why does the 59n relay keep tripping the breaker?
The 59 relay is an overvoltage relay. The 59N relay is an overvoltage relay for the neutral circuit. Check neutral and make sure the system is properly balanced.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
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.
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.

Where I'm from, it's called a "circuit breaker".A circuit breaker.
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.
What is difference between isolation transformer and earth protection relay?
An isolation transformer is a mutual transformer having a voltage ratio of 1:1, so that the secondary circuit is electrically isolated from the primary circuit, yet subject to the same voltage.An earth protection relay is a category of protective relay that responds to an earth fault monitored by a current transformer (CT). In the event of an earth fault being detected by the CT, the relay with activate the trip circuit to a circuit breaker which will then disconnect the fault.
Is there a relay switch or circuit breaker on a 94 sts?
There are multiple relays and circuit breakers in that vehicle.
Why does a lawn mower keep popping the relay circut breaker?
you have a short to ground in the electrical circuit that that breaker is on.
What is ocr efr uvr referred to in air blast circuit breaker?
ocr-over current relay(senses the over current in the circuits) efr-earth fault relay uvr-under voltage relay
What is the difference between Earth Fault Relay and Earth Leakage Relay?
Earth leakage relays are instantaneous tripping relays where as earth fault relays have the option of time and ampere setting i.e. for a setted ampere the circuit breaker will be tripped off after the setted time (in second).
How do you express an earth leakage circuit breaker?
In North America they are known as a GFCI. Ground Fault Circuit Interrupter breaker.
What is function of damping relay in circuit breaker?
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
