Product details

It protects a single pole plus neutral (1P+N) in AC distribution circuits at 50/60 Hz. Breaking capacity is 6000 A Icn at 230 V AC, certified to EN/IEC 60898-1.

Depth is 78 mm, height 81 mm. IP20 finger-safe terminals; the breaker is intended for enclosed distribution boards, not open-panel washdown areas. Tightening torque 2 N.m, strip length 13 mm. The toggle gives local ON/OFF indication. Earth-leakage protection requires a separate block — not integrated.

No direct pin-compatible alternative exists within the same iDPN N range at this rating and curve — the D-curve 10 A 1P+N is the only variant at these parameters.

Durability and environmental ratings

Electrical and mechanical durability both rated at 20,000 cycles. Suitable for isolation (full disconnection on the protected pole).
