There are two types of residual current circuit breakers in use today: magnetic and thermal. Magnetic residual current circuit breakers (MRCB) are designed to detect any electrical leakage from switched off devices, while thermal residual current circuit breakers detect heat generated by electrical equipment.
When the magnets detect a change in electrical charge, it triggers a tripping mechanism to open the circuit. Thermal Residual Current Circuit Breakers (TRCBs): TRCBs are similar to MRCBs, but instead of using a magnet to sense electron flow, they use a heating element to sense the presence of heat. If enough heat is sensed, the TRCB activates.
Thermal Residual Current Circuit Breakers (TRCBs): TRCBs are similar to MRCBs, but instead of using a magnet to sense electron flow, they use a heating element to sense the presence of heat. If enough heat is sensed, the TRCB activates. As a result, they are often used in large power transformers with high voltages and currents.
A automatic fuse (MCB) is a type of electrical switch that can cut the electrical current flowing through its contacts when overheating occurs. This prevents damage to the protected circuit. The circuit breaker has three pins connected to each other. One pin is connected to ground. The second pin connects to VCC (Power).
Magnetic residual current circuit breakers (MRCB) are designed to detect any electrical leakage from switched off devices, while thermal residual current circuit breakers detect heat generated by electrical equipment. Both types of circuit breakers can be used in residential and commercial buildings.
A typical household circuit breaker has two settings; normally open and normally closed. When the switch opens, it should stay in this position until the current flow reaches a safe value. If the current exceeds a set limit, the breaker trips and opens the circuit. There are different types of automatic circuit breakers, but they all work the same.
