mainly used in power supply system such as power distribution room, distribution cabinet and other important power supply system, For installation at LPZ 0B -2 or higher, specially designed for TN-S system. Applied in SPD Class I (Class B) for various power supply system of lightning current surge protection. Designed according to IEC 61643-1/GB 18802.1.

Main character:

1. Three-phase protection for TN-S system

2. Pluggable module, high discharge capacity, quick response

3. Double thermal disconnection devices, providing more reliable protection

4. Multifunctional connection for conductors and busbars.

5. Green window will change when fault and also provide remote alarm control at the same time

Parameters:

When the SPD fails in breakdown for over-heat and over-current, the failure release will help electric device separate from the power system and give the indication signal, green means normal, red means abnormal, it's also could be replaced for the module when has operating voltage.

Product Features
- Inside over-current and over-heat protection, temperature control open circuit.
- Module design, convenient installation, could be replaced online.
- Smallness leak current, response quickly, less residual voltage.
- Signal indication device, green (normal), red (abnormal).
- New technology, highly energy, clearance discharge pole (N-PE)
