Improve Security

If you are worried about electricity safety problems, a residual current circuit breaker will be a good choice. It features Leakage protection with low voltage distribution. 

Long service life

The number of times to tum on/off the rated current under the maximum working voltage is more than 10000.（Data from the inspection report of Zhejiang low voltage electrical products quality inspection center.）

Visible Safety

The RCCBs Focus on Circuit Protection to upgrade the safety system, prevent short circuit hidden danger, overheating and overload. Make sure to rest your assured life.

Visualization Window

The circuit breaker protection trips if the circuit has leakage, please pay attention to check the circuit. You can also manually turn it on or off.

D-Handle

An ergonomic  D-shaped design can reduce pressure and fluctuation, it helps to create a steady state.

​

Ambient Temperature

This RCCB has strong adaptability to meet the application requirements at extreme temperatures.

Application

You can use the breaker on various occasions. It can apply to the frequency converter, uninterruptible power supply unit, electric vehicle charging system, Photovoltaic (PV) system, Welding equipment, electric vehicle charging system and so on.

B Type Features

B Type Residual Current Circuit Breaker(RCCBs), in addition to normal AC, can detect high-frequency AC and pure DC earth leakage currents. It can reduce the risk of fire and electrocution through automatic disconnection of the electrical supply, relying on the selection of the correct type of RCCB. 'B' Type Applications required application: EV & PV installations, Frequency converters UPS installations, High-frequency power converters, Building site power supply cabinets.​
