The Siemens SIRIUS 3RV2011-0DA20-ZX95 is a size S00 motor protection circuit breaker rated for Trip Class 10, with a breaking capacity of 100 kA at 400 V AC. It includes phase failure detection and uses spring-loaded terminals for the main circuit.
Mounting and integration
Mounts via screw fixing or snap-on onto a 35 mm standard mounting rail per DIN EN 60715. Any mounting position is allowed. Dimensions: 45 mm wide, 106 mm tall, 97 mm deep. Clearance: 50 mm above and below, 30 mm at the sides, no forward or backward clearance required.
Key ratings and what they mean
Trip Class 10 means the breaker will trip within 10 seconds at 7.2× the thermal setting — standard for protecting standard induction motors during start-up. The 100 kA breaking capacity at 400 V AC ensures it can safely interrupt high fault currents without upstream damage, suitable for high-capacity industrial panels. Phase failure detection protects motors from single-phasing, a common cause of winding burnout.
