Product details

It offers a 3 kA breaking capacity according to EN 60898, which certifies its performance for overcurrent protection in residential and commercial installations. The IP20 protection class means it is touch-safe but not sealed against moisture — suitable for indoor panel mounting where no washdown or condensation is expected.

Integration notes

Rated for overvoltage category 3 and energy limiting class 3, this breaker is designed for fixed installation in distribution boards where it provides both overload and short-circuit protection. The neutral conductor switching function (2-pole switching) ensures both phase and neutral are disconnected, which is required for some local wiring codes and for isolating circuits where the neutral is not solidly bonded.
