The surge protection device (SPD) series is suitable for low-voltage power supplies and

distribution system to protect the device from surge and inductive transient voltage

by lightning strike or internal power supply system with the following features:

◆ Shockproof and flame retardant plastic

◆ High discharge capacity with waveforms up to 40kA (8/20μs) for single module

◆ Automatic fault release device for over-current, over-temperature protection can effectively prevent the appearance of fire

◆ Support hot replacement

◆ Local signal alarm and remote switching signal warning mode;

◆ 35mm DIN rail mounting
