Feature●Product parameters: 1P+N ----25A----UN230V●Product function: leak protection, short circuit protection, overload protection.●Product wiring: The top end enters the wire, the lower end leaves, the wire under tension is on the left side and the neutral wire is on the right.●Function difference: the leak protection not only tears when the current is too large, but also in case of leaks.●Product selection: If you select a circuit breaker, you need to choose a circuit breaker with a lower current than that of the wire. For example, the maximum current of a BV2.5 square wire is 25A, and the circuit breaker must be less than 25A.Description Leak protection device, called leak switch, also known as leak switch, is mainly used to protect the electric shock of the person with risk of death when the equipment has leak protection device. The short circuit can also be used as a rare line switching start under normal conditions.
