The 4-module-width footprint (72 mm wide) occupies four 18 mm DIN-rail positions — plan your enclosure fill accordingly. This breaker switches the neutral conductor (3P+N), so it opens all live conductors on a fault — required in many European and IEC-based installations where the neutral is not bonded to ground downstream. The combined terminal design at both top and bottom accepts a range of conductor sizes and busbar comb profiles, simplifying panel wiring.
Derating and environmental limits
The 13 A rating is at 35 °C ambient. At 40 °C it derates to 12.38 A, at 50 °C to 11.73 A, and at 60 °C to 11.02 A — a roughly 15% drop from the nameplate at the top end of the operating range. Ambient temperature range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% up to 75 °C.
The breaker is certified to IEC / EN 60898-1 (the standard for household and similar installations) and IEC / EN 60947-2 (the industrial standard for low-voltage switchgear and controlgear), plus UL 1077 for supplementary protection in North American panels. Overvoltage category III (fixed installation) and energy limitation class 3 apply.
