circuit breakers provide two basic forms of protection: overcurrent and short circuit The mechanism used on most simple breakers for overcurrent is a calibrated bimetalic strip > when it draws two much current it gets hot and bends the strip to trip a mechanical arm The mechanism used for short circuit is a electro-magnetic coil > when a fault current goes through the coil, it magnetically attracts a ferrous lever that trips a mechanical release Many larger breakers have electronic trips which monitor the above two functions plus others functions electronically, and a microprocessor then desides to trip the mechanical release

An automatic circuit breaker works by detecting an electrical overload or short circuit in the circuit it is protecting. When it detects a fault, it quickly interrupts the flow of electricity to prevent damage to the circuit or appliances. This is done through a bimetallic strip that bends when heated by the excess current, causing the breaker to trip and disconnect the circuit.

Who invented the electromagnetic brake and automatic circuit breaker?

The electromagnetic brake was invented by a French engineer named Georges Hilaire Marie Claude Renior in the 1950s. The automatic circuit breaker was invented by Thomas Edison in the late 19th century.


Need of isolator on both side of circuit breaker?

Before anyone is allowed to work on a high-voltage circuit breaker, it must be tripped, electrically isolated, earthed (grounded), barriers/warning notices put in place, and a permit to work document issued by an engineer to the senior member of the maintenance crew. 'Isolation' means a physical (and visible) break in the conductors between the circuit breaker and any potential source of supply -and this is provided by placing isolator switches on each side of the circuit breaker. Without these isolators, the circuit breaker would remain energized, even though the circuit has been broken by the circuit breaker.


What is a Circuit breaker and explain type circuit breakers?

A circuit breaker is an electrical device that automatically interrupts the flow of electricity in a circuit when it detects a fault or overload, to protect the circuit from damage. There are several types of circuit breakers, including thermal, magnetic, and gas-insulated circuit breakers, which operate based on different principles to ensure the safe operation of electrical systems.

Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?

A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.

How does an open circuit occur?

An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.
