The Residual Current Circuit Breaker - RCCB 2P 40A EH(x) 2x40 refers to two-phase devices with the ability to work in a network with a current of 40A. Such equipment must necessarily be present in every building, regardless of whether it is industrial or residential, as this is your protection from the danger of overload in the power supply network. The RCCB is made of high quality white plastic that does not propagate burning. This RCCB device protects against the dangerous consequences of a short circuit in case of overload in the network, as it is intended for its timely opening. With high voltage, the wiring may simply ignite and set fire to the building itself. To choose the product you need, contact the consultants of our website.
