It carries a 15 kA interrupting rating per EN 60898 and a 40 kA rating per IEC 60947-2, with a 5 kA rating under UL 1077 — so the same unit covers IEC and North American installations without swapping variants. The 54 mm width (3 modular units) snaps onto standard DIN rail; the quick-assembly system and combined top/bottom terminals speed panel wiring.
Breaking capacity and standards
Three interrupting ratings on the nameplate: 15 kA at 400 V AC per EN 60898-1 (the domestic/commercial standard), 40 kA at 400 V AC per IEC 60947-2 (the industrial standard), and 5 kA per UL 1077. DC rating is 15 kA at 60 V per IEC 60947-2, with a max DC operating voltage of 72 V.
Rated for -40 °C to 75 °C ambient, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Pollution degree 3 (conductive pollution typical of industrial enclosures). Halogen-free and silicon-free construction. Sealable terminals allow lockout/tagout compliance.
