The Siemens SIRIUS 3RV2011-1HA15-ZW97 is a motor protection circuit breaker, Class 10, designed to protect motors against overload and short circuit. It provides phase failure detection and mounts on a 35 mm DIN rail per DIN EN 60715. The interrupting capacity reaches 100 kA at 400 V, meaning it can safely clear high-fault currents in a motor branch circuit without upstream coordination issues.
Mounting and Integration
Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width fits standard panel spacing; depth is 97 mm. Clearance requirements: 50 mm above and below, 30 mm to the side, 0 mm forward and backward. Accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire at the main contacts (M3 screws).
Ratings and Duty
Trip Class 10 means it disconnects within 10 seconds at 7.2x motor FLA — standard for general-purpose induction motor protection. Phase failure detection is built in, so a lost phase trips the breaker. Rated operational voltage range is 20 to 690 V. Short-circuit breaking capacity: 100 kA at 240 V and 400 V, 42 kA at 500 V, 4 kA at 690 V. Fuse backup ratings: gL/gG 50 A at 400 V, 40 A at 500 V, 35 A at 690 V. Maximum operating rate in AC-3 duty is 15 operations per hour.
