At DC, the part is rated 15 kA per IEC 60947-2, and under UL 1077 / CSA C22.2 No. 235 it carries 5 kA. That spread means the same breaker can serve panels specified to different regional standards — useful for a machine builder shipping globally. Rated operational voltage is 400 V AC (440 V max for multi-phase or single-phase operation), with a DC rating of 60 V (72 V max). That covers most 400 V three-phase distribution and 48–60 V DC control circuits, but not 125 V DC buswork — watch the voltage if you're paralleling batteries.
Designed to IEC/EN 60898-1 (MCB standard for household and similar installations) and IEC/EN 60947-2 (low-voltage switchgear and controlgear for industrial use), plus UL 1077 / CSA C22.2 No. 235 for North American supplementary protection. The dual-standard rating means it qualifies for both IEC-based distribution panels and UL 508A industrial control panels — one part number for both worlds. Rated for ambient temperatures from -40 °C to +75 °C, with derating above 55 °C per the humidity/temperature influence table: max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C.
The breaker carries combined terminals on both top and bottom (screw and clamp combinations per the datasheet), accepts copper conductors, and is sealable for tamper-proof applications. Neutral conductor switching is not provided — it's a 3-pole device for three-phase loads, not a 3P+N configuration.
