RC-7 Residual Current Device

RC-7 Residual Current Device

Description
Residual current device (RCD), sometimes called "safety switch" or simply "RCD" in Australia, is manufactured to prevent electrocution by detecting the leakage current that is far smaller than the currents needed to operate conventional circuit breakers or fuses.

Features
1. Residual Current Device (RCD) conforms to the standard of IEC61008.
2. This vacuum circuit breaker can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunk line.
3. Thereby it can be used to avoid the shock hazard and fire caused by earth leakage.

Application
1. This type of electrical switch is used extensively in various plants, enterprises, buildings, construction, commerce, hotels and families.
2. It can be used in circuits of 1 phase 230V and 3 phase 400V 50/60Hz.
