Function
The surge protective device (SPD) protects AC electrical installations and connected equipment from transient overvoltages caused by lightning or switching operations.
Using MOV + GDT hybrid technology with an integrated circuit breaker, it diverts surge energy safely to ground while limiting the residual voltage to protect downstream devices.
It provides coordinated type 2 protection in common and differential modes and includes remote signaling for monitoring.
