The Siemens 3RV2011-1DA15-ZW97 is a SIRIUS motor protection circuit breaker, designed for motor protection with phase failure detection and Trip Class 10. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a 45 mm wide footprint. Rated voltage spans 20 to 690 V, with a breaking capacity of 100 kA at both 240 V and 400 V, and 10 kA at 690 V.
DIN rail fit and clearance
At 45 mm wide, 97 mm deep, and 97 mm tall, this breaker occupies a standard single-module footprint on the DIN rail. Clearance requirements: 50 mm above and below, 30 mm to the side, zero forward or backward — so it can sit flush against a backplate or panel door without extra breathing room.
Trip Class 10 and switching duty
Trip Class 10 means the breaker trips within 10 seconds at 7.2× the thermal setting — standard for standard-duty motor starting where the inrush doesn't linger. Maximum switching frequency is 15 operations per hour in AC-3 and AC-3e duty, which covers most pump, fan, and conveyor applications. Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, and 0.15 A at 60 V.
