It offers a gL/gG fuse backup rating of 25 A at 400 V and 690 V, and 32 A at 500 V, so the upstream fuse coordinates with the breaker's magnetic trip to clear high faults. Breaking capacity hits 100 kA at 240 V, 400 V, and 500 V, dropping to 10 kA at 690 V — sufficient for most industrial panel secondary-side faults. ## Panel fit and DIN-rail integration Width is 45 mm, depth 97 mm, height 106 mm — a standard 45 mm module that occupies one slot on a 35 mm DIN rail per DIN EN 60715, with screw and snap-on fastening. Clearance requirements: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards — meaning the breaker can sit flush against the back panel and the door, but needs breathing room above and below for arc exhaust and wiring access. Maximum switching frequency under AC-3 duty (motor starting) is 15 operations per hour, and the same limit applies under AC-3e — so it's sized for occasional starts, not a jogging or inching application.","metaTitle":"Siemens 3RV2011-1DA20-ZX95 SIRIUS Motor Circuit Breaker, Cla","metaDescription":"Siemens 3RV2011-1DA20-ZX95 SIRIUS motor-protective circuit breaker, Class 10 trip, 100 kA at 400 V, 45 mm wide, snap-on DIN rail.
