General                                                                                 
This series consists of MOV power modules and a base, and is used for second-level protection of L-PE and N-PE. It applies in low voltage AC power distribution systems, and is connected between the AC power supply and the equipment in parallel. It protects the equipment from impulse surge and transient overvoltage caused by the outside environment (such as lightning and EMI) or by the system (such as switching effects of the system, startup or shutoff of the inductance and capacitance loads).

Features                                                                                 
1. Anti-reverse plug.
2. High discharge capacity, low residual voltage.
3. Overheating protection.
4. Failure indication and centralized remote signalling alarm dry contacts.
5. Degree of protection IP20, flammability UL 94 V-0.
