BCH Electric offers 30mA RCCB options for applications requiring a high level of protection against direct and indirect contact with leakage current. The device continuously compares current flowing through live and neutral conductors and trips when the residual imbalance exceeds its sensitivity. Ratings of 25A, 40A and 63A are available. Contact BCH Electric today to discuss a 30mA RCCB for suitable residential, commercial or workplace electrical circuits.
