The residual current circuit breaker is suitable for electrical circuits with a rated voltage of 230/400 V AC, a frequency of 50/60 Hz and a rated current of up to 40 A.
Earth leakage circuit breaker 63A - 300mA Type B
With the diversification of energy use and equipment, the interactive use of alternating and direct current, and products with many different waveform signals, we need higher-level residual current protection circuit breakers to protect our personal safety and avoid the danger of electric shock.
Type B RCD RCCB General :
Type B RCDs, in addition to normal alternating current, can detect high-frequency AC and pure DC earth leakage currents.
Reducing the risk of fire and/or electrocution by automatically disconnecting the power supply relies on selecting the right type of RCCB.
The RCCB offers mutual protection to the operator's body in conditions where exposed live parts must be connected to a suitable grounding post. The RCCB also offers protection against the fire hazard caused by ground fault current due to a malfunction of the overcurrent protection device.
Advice:
- RCCB with rated sensitivity up to 10mA could be used as an additional protective device in the situation where the protective device fails. RCCB
- designed for domestic installation and similar applications, is generally used for non-professional operation (no maintenance required) .
- RCCB provides protection against electric shock resulting from direct contact of the two protected lines, or leakage current between these two lines.
- It is recommended to install special devices such as surge protection devices, a lightning arrester, etc. on the line upstream to the RCCB as a precaution against the potential voltage and surge current occurring at its supply input .
