  • max wire size: 2.5…25 mm² (tunnel terminals, rigid or flexible)



Function

The surge protective device (SPD) protects AC electrical installations and connected equipment against transient overvoltages caused by lightning and switching operations.
Using MOV + GDT hybrid technology with an integrated circuit breaker, it safely diverts surge energy to ground while maintaining coordinated Type 2 and Type 3 protection.
It provides protection in differential and common modes across all phases and neutral and includes remote signaling for monitoring.
