Function
The surge protective device (SPD) protects AC electrical installations and connected loads against transient overvoltages caused by lightning or switching operations.
Using MOV + GDT hybrid technology with an integrated disconnector, it safely diverts surge energy to ground while limiting the residual voltage to protect downstream equipment.
It provides coordinated Type 2 protection in L/N, L/PE and N/PE modes and includes remote signaling for monitoring.
