What it is and what it does
The Siemens 3RV2011-0KA10-ZW96 is a SIRIUS motor protection circuit breaker designed for motor protection duty, with Trip Class 10 and phase failure detection built in. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a 45 mm wide footprint in the panel. Rated breaking capacity reaches 100 kA at 400 V AC, 500 V AC, and 690 V AC — enough to handle high-fault-current scenarios without cascading upstream. The screw-type main circuit terminals accept 2x (0.75–2.5 mm²) solid or stranded, or 2x 4 mm².
Clearance and mounting
Clearance requirements are specified: 50 mm above and below, 30 mm at the sides, 0 mm forward and backward. Mounting position is any, so orientation in the enclosure is flexible. The 97 mm depth and 97 mm height define the envelope.
