The Siemens SIRIUS 3RV1011-0EA10-ZW97 is a motor protection circuit breaker designed for motor loads up to 0.1 kW at 230 V. It provides a 100 kA breaking capacity at 400 V, meaning it can safely interrupt fault currents up to that level without cascading upstream — critical for panel coordination in a motor branch circuit. Trip class is CLASS 10, so it clears a locked-rotor condition within 10 seconds at the rated current — standard for general-purpose motor protection on pumps, fans, and conveyors where the motor can tolerate a brief stall without damage. Phase failure detection is built in, so the breaker trips if one phase drops out — preventing single-phasing damage on a three-phase motor.
Mounting and Integration
Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width (three module spaces) fits standard panel layouts; depth is 75 mm, height 90 mm. Clearance requirements: 20 mm upward, 20 mm downward, 9 mm at the side — no extra space needed forward or backward. Terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper. Screw-type main contacts use M3 screws. Mounting position is any, so it fits vertical or horizontal DIN-rail runs without derating.
