Electronic Type RCCB

Principle of operation

The operating principle of the Electronic Type RCCB is based on the principles of electromagnetic induction and current balancing. When the phase and zero line currents in the circuit are unbalanced, i.e. residual current exists, the current transformer inside the RCCB will detect this unbalance and generate a corresponding signal. This signal, after being processed by the electronic circuit, will trigger the action of the release mechanism, so that the circuit breaker will quickly cut off the circuit.

Main Features

High sensitivity: Electronic RCCBs are able to detect very small residual currents, usually less than 30mA or even lower.

Fast action: Once the residual current is detected to exceed the preset value, the RCCB will act immediately to cut off the circuit and prevent accidents.

Safe and Reliable: RCCB adopts advanced electronic components and microprocessor technology to provide higher reliability and stability.

Easy to install and maintain: Electronic RCCBs usually have a compact structure and simple wiring, making them easy to install and maintain.

Application Scenarios

Electronic RCCBs are widely used in a variety of situations where electrical protection is required, including but not limited to:

Residential and commercial buildings: used to protect electrical equipment and personal safety, preventing electric shock accidents and electrical fires.

Industrial production lines: used to protect electrical equipment such as motors and transformers from normal operation, preventing equipment damage and downtime due to leakage and overload.

Public facilities: such as hospitals, schools, libraries and other places, used to ensure the safe operation of electrical equipment and the safe use of electricity by personnel.
