Any mounting position is allowed, which simplifies panel layout — no derating for horizontal vs vertical orientation. Dimensions are 45 mm wide by 106 mm high by 97 mm deep, so it occupies a standard 45 mm module width on the rail. Clearance distances: 50 mm above and below, 30 mm to the side, and zero forward or backward — meaning it can be stacked against the back panel or enclosure wall without extra air gap. No screw torque to verify — just strip and insert. It is still the active catalog number from Siemens for this rating and frame.","metaTitle":"Siemens 3RV2011-0KA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2011-0KA20 SIRIUS motor protection circuit breaker.
