The 2 Pole RCCB 40 Amp RCD is suitable for circuits with a rated voltage of 230/400V AC, a frequency of 50/60Hz, and a rated current of 125Amp or less.
RCCB provides protection against fire hazards caused by ground fault currents caused by malfunction of the overcurrent protection device.
Its working principle is to provide indirect protection to the operator’s body under the condition of exposing live parts. It should be connected to an appropriate grounding electrode.
It is extremely important to pay attention to the safety of electricity use, and it is also extremely important to choose a good-quality leakage protection device.
2 Pole RCCB 40 Amp Special tips:
1. RCCB is designed for non-professional home installation and other similar applications. And no maintenance is required.
2. The RCCB with a rated sensitivity of 10mA can be used as an auxiliary protection device to prevent other protection devices from being unable to prevent electric shock.
3. RCCB provides protection against electric shock caused by direct contact between two protected lines or leakage current between the two lines.
5. In order to meet the above conditions and applications, RCCB with “ON-OFF” indicating device is considered suitable for isolation function.
