The JDL-I leakage relay is combined with an AC contactor or circuit breaker to form a leakage protection device. Due to the use of the new technology of phase and amplitude detection, it eliminates the insensitivity and dead zone during electric shock, automatically distinguishes between leakage and electric shock, and has various functions such as energy saving and noise reduction.

The product complies with standards such as GB6829-95 and JB8756-98, and is recommended for the national "two networks" renovation.

Scope of application

Suitable for low voltage (380/220V) distribution systems with a neutral point directly grounded, the main function is to provide indirect contact protection against fatal electric shock to individuals. Especially suitable for use in power grids with poor line conditions and unbalanced three-phase leakage, to improve the safe operation capability of the power grid.
