JD6L Phase detection and amplitude leakage relay

Main purpose and scope of application:
JD6L series phase and amplitude detection leakage relays are combined with AC contactors or circuit breakers to form leakage protection devices. It is suitable for low-voltage (380/220V) power distribution system where the neutral point is directly grounded. The main function is to provide indirect contact protection for the leakage of lines and equipment. Due to the new technology of phase and amplitude detection, the insensitivity of electric shock is eliminated, and it has the characteristics of energy saving and noise reduction. It is especially suitable for the use of power grids with poor line conditions and unbalanced three-phase leakage to improve the safe operation of the power grid.
This product complies with: National Standard GB/Z6829, GB/T22387.

Model and meaning

Structural features
1. In the case of unbalanced three-phase leakage, electric shock and electric leakage can
operatereliably;2. It can be put into operation normally under the condition of low insulation level of the line and large leakage current;
3. Strong anti-interference, lightning, Under the interference of power grid harmonics and transient over-voltage of the line, no malfunction;
4. No action when the line leakage is suddenly reduced, which reduces unnecessary power outages and has a high commissioning rate;
5. Energy-saving silent operation is in contact with the mating The working voltage of the coil of the device is 380V and 220V, which can be used for long-term operation without burning the coil;
6. There is a test power transmission function when themachine isturned on. 20~30 seconds after tripping, automatic reclosing, safe and labor-saving;
