63A/100mA Residual Current Circuit Breaker RCCB

Principle of operation

The operating principle of the RCCB is based on the principles of electromagnetic induction and current balance. When the residual current in the circuit passes through the transformer, the transformer generates a corresponding magnetic flux. This magnetic flux is converted into an electrical signal and processed by an electronic circuit. When the processed electrical signal reaches a preset threshold, the RCCB triggers the release mechanism to act, causing the circuit breaker to quickly cut off the circuit.

Main Features

High sensitivity: The RCCB is capable of detecting small residual currents, usually less than 30mA (exact value depends on product specifications), which helps to cut off circuits in time before electrocution accidents occur.

Fast Response: RCCB can quickly cut off the circuit within a few milliseconds after detecting the residual current, which effectively prevents electric shock accidents and the spread of electrical fires.

Safe and Reliable: RCCB adopts advanced electronic components and disconnecting mechanism with high reliability and stability. At the same time, it also has overload and short-circuit protection functions, which can fully protect the safety of circuits and equipment.

Easy to install and maintain: RCCB usually adopts modular design, compact structure and easy to install. It also has easy-to-inspect and replace contacts for routine maintenance and inspection.

Application Scenarios

63A/100mA Residual Current Circuit Breaker RCCB is widely used in a variety of situations where electrical protection is required, including but not limited to:

Residential and commercial buildings: for the protection of electrical equipment and personal safety against electric shock accidents and electrical fires. In homes, RCCBs are usually installed in distribution boxes as the main or branch protection for home circuits.

Industrial production line: It is used to protect the normal operation of electrical equipment such as motors, transformers, etc., and prevent equipment damage and shutdown caused by leakage and overload. In the industrial field, RCCBs are usually installed at the power inlet end of electrical equipment as the protection device of the equipment.

Public facilities: such as hospitals, schools, libraries and other places, RCCBs are used to ensure the safe operation of electrical equipment and the safe use of electricity by personnel. These places usually have higher requirements for electrical safety, so RCCBs are more widely used.
