RCCBs – Selective Product Range Type S (delay)

The selective Residual Current
Circuit Breakers are available with 100, 300 mA sensitivity in 2 and 4 pole version.

A selective RCCBs is time delayed ( min. 300ms at IØn). And it is commonly used as a main breaker to prevent nuisance tripping due to transient overvoltages and provide discrimination with the downstream standard RCCBs.
