JD26 Residual current operated relayDetailed product description：

The JD26 phase and amplitude detection residual current relay is combined with an AC contactor or circuit breaker to form a residual current protection device, suitable for low-voltage (380/220V) distribution systems with a neutral point directly grounded. Its main function is to provide indirect contact protection against fatal electric shock to individuals. Due to the adoption of the new technology of phase and amplitude detection, the insensitivity and dead zone during sudden changes have been eliminated. It can automatically distinguish between gradual (leakage) and sudden (electric shock) currents, and has various other functions such as energy saving and noise reduction to improve the safe operation capability of the power grid.
