Breaking capacity at 400 V is 100 kA — that is a high-fault rating for a 45 mm wide device, meaning it can handle a direct short on a 400 V bus without needing upstream fuses in most panels. ## Breaking capacity and motor sizing Breaking capacity varies by voltage: 100 kA at 400 V, 42 kA at 500 V, and 4 kA at 690 V. Motor horsepower ratings are given per voltage: 3 hp at 220/230 V, 5 hp at 460/480 V, and 10 hp at 575/600 V. For a 460 V motor rated 5 hp, this breaker covers the full-load current and the locked-rotor curve within Class 10. Depth is 97 mm, height 106 mm. That means you can pack breakers side-by-side with no gap between them, but you need headroom above and below for the arc-chamber venting and terminal access.","metaTitle":"Siemens 3RV2011-1JA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2011-1JA20-ZX95 SIRIUS motor protection circuit breaker, Class 10, 100 kA breaking capacity at 400 V, spring-loaded terminals, DIN rail mount.
