Ground fault detection is not included, so if that's required, an external ground-fault module or relay must be added downstream. The continuous current rating of 12 A sets the motor FLA it can protect. At 400 V, that corresponds to a 5.5 kW motor. The breaker also carries a 690 V rated insulation voltage and a 6 kV rated surge voltage resistance, covering most industrial supply systems. In a crowded enclosure, that heat adds up — allow adequate ventilation or derating if ambient exceeds 60 °C. The 81 mm depth fits standard 100 mm deep enclosures. Compliance documentation includes RoHS substance prohibition dated 01.01.2013. The front face carries IP20 finger-safe touch protection.","metaTitle":"Siemens 3RV1011-1KA20-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1KA20-ZW95 SIRIUS motor protection circuit breaker, 12 A continuous, Trip Class 10, 5.5 kW at 400 V, 50 kA breaking capacity at 400 V AC.
