It includes phase failure detection, which means it will trip if one phase drops out — a common failure mode that can single-phase a motor and burn it out if left uncorrected. The 45 mm width fits standard DIN-rail spacing; depth is 97 mm, which leaves clearance for wiring in a standard 200 mm deep enclosure. Spring-loaded terminals on the main current circuit accept 2x 0.5–4 mm² solid or stranded — no lug crimping needed, just strip 8 mm and push in. ## Ratings and coordination Rated operating voltage covers 20 to 690 V. The 100 kA breaking capacity at 400 V means it can clear a bolted fault on a 400 V supply without upstream fuses needing to coordinate — that is a high SCCR for a motor-protection breaker in this frame size. At 690 V the breaking capacity drops to 4 kA, so verify the available fault current if running a 690 V line. The trip class 10 means it will disconnect within 10 seconds at 7.2× the thermal setting — standard for general-purpose motor starting.","metaTitle":"Siemens 3RV2011-1FA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2011-1FA20 SIRIUS motor protection circuit breaker, Trip Class 10, 100 kA at 400 V, phase failure detection, spring-loaded terminals.
