3 Phase RCCB Residual Current Circuit Breaker is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 125Amp.
Under the condition of exposed live parts, 3 Phase RCCB provides indirect protection to the operator’s body，It should be connected to an appropriate ground electrode.
Not only that, 3 Phase RCCB also provides protection against fire hazards the ground fault current caused by the malfunction of the overcurrent protection device.
It has many advantages and plays an important role in life scenes such as family and industry.
3 Phase RCCB Special tips:
- The RCCB with a rated sensitivity of up to 30mA can be used as an auxiliary protective device to prevent other protective devices from being unable to prevent electric shock.
- RCCB is designed for non-professional home installations and other similar applications.
- It is recommended to install special devices on the upstream line of the RCCB, such as surge protectors, lightning arresters, etc., to prevent potential surge voltage and current from appearing on the power input side.
- In order to meet the above conditions and applications, RCCBs with “ON-OFF” indicating devices are considered suitable for isolation functions.
