ZGGB40-385(3+1)
General
The ZGGB40-385(3+1) Modular Power Supply SPD consists of three MOV power supply modules, one GDT power module, and a base. It provides second-level protection for L-N and N-PE and its operating status can be monitored remotely. 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-plug and mutual-plug protection
2.No backup fuse needed
3.High discharge capacity, low residual voltage
4.Overheating and over-current protection
5.Failure indication and centralized remote signalling alarm dry contacts
