TNR-C series of protectors are mostly used to distribution box and low voltage switchgear cabinet.

The TNR-D series protectors are suitable for the terminal protection of the electric equipment. It can be installed in the electronic and electrical equipment, distribution box at the floor, and the communication equipment.

1. disconnecting device
When the surge protective device is overheated or breakdown due to deterioration, the failure device can automatically detached it from the power grid, and at the same time, window shon red (window) l. (the normal window displays green), which indicates that the protector is invalid and needs to be replaced immediately.

2. Remote control warning instructions:
Normal close and Normal open, When SPD breakdown or failure. the Remote Control warning (the rated capacity of the telegraph contact: 250V3 (0.5) A).

3. The characteristics of 2+PE and 4+PE:

The conventional 2P and 4P products, the core protection device L-PE and N-PE were MOV, with the deterioration of the installation environment and the use of time longer, there will be weak leakage current , the micro current of power and equipment will not cause harm, but if the front end when there is leakage protector, leakage protector can cut off power supply.
Therefore, our innovation is in the PE loop is connected in series with no leakage protection devices (flow discharge tube), completely solve the leakage current, more security of power grid and equipment, not only to extend the life of the product, to achieve the purpose of no maintenance, at the same time, it will not cause the front end leakage protection misoperation device.
