The Siemens 3RV2011-0EA10-ZW97 is a SIRIUS motor protection circuit breaker in size S00, designed for motor protection with a Class 10 trip characteristic. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, fitting into standard panel layouts with a 45 mm width and 97 mm depth.
Breaking capacity and trip class
Rated breaking capacity hits 100 kA at 400 V AC, 500 V AC, and 690 V AC — that means it can safely interrupt fault currents up to 100 kA at those voltages without cascading upstream. The Class 10 trip ensures the breaker opens within 10 seconds at 7.2× the thermal setting, matching standard motor starting curves for pumps, fans, and compressors.
Protection and wiring
Phase failure detection is built in, so a lost phase on the line side trips the breaker instead of cooking the motor on single-phase current. Screw-type terminals on the main circuit accept 2x (0.75…2.5 mm²) solid or stranded, or 2x 4 mm² — M3 screws on the main contacts, Pozidriv size 2 tip.
