The rated breaking capacity is 10 kA per EN 60898-1 and 20 kA per IEC 60947-2 — the higher figure applies when the breaker is used in industrial distribution per the 60947-2 standard, giving headroom for high-fault installations. Under UL 1077, the interrupting rating is 5 kA, which governs North American supplementary protection applications.
The quick-assembly fastening system allows snap-on mounting in any position. Installation depth is 70 mm, with an overall depth of 76 mm — account for this when routing wire behind the DIN rail. IP20 is achieved only with connected conductors — the front terminals are finger-safe, but the busbar area is not sealed against dust ingress.
Humidity derating applies: 95% RH up to 55 °C, then 55% RH up to 70 °C, then 35% RH up to 75 °C — a consideration for sealed enclosures or high-humidity washdown areas. Pollution degree 3 means it tolerates conductive pollution in industrial atmospheres.
Standards and documentation
Certified to IEC / EN 60898-1 for residential and commercial MCB applications, and IEC / EN 60947-2 for industrial circuit-breaker duty. For North America, UL 1077 supplementary protection listing is included. The frequency rating is 50/60 Hz. The brand provides RoHS and REACH declarations as standard; UL and CSA documentation are available on request as part of the SENTRON technical file. Energy limitation class 3 indicates the breaker limits let-through energy to a level suitable for protecting downstream components in a coordinated selective system.
