The 45 mm width (3-module DIN footprint) and 97 mm depth let it drop into a standard 3RV cutout. Clearance: 50 mm above and below for arc venting, 30 mm to the side, zero forward or backward. Any mounting position works. ## Interrupting & coordination The 3RV2011-1KA10-ZX95 carries a 100 kA interrupting rating at 240 V and 400 V, 42 kA at 500 V, and 4 kA at 690 V. The gL/gG fuse limits at the same voltages: 63 A at 400 V, 50 A at 500 V, 40 A at 690 V. If your panel has a 65 kA SCCR requirement, this breaker meets it at 400 V without extra hardware. The 3RV2023-4DA10 steps up to a higher current range (typically 22–32 A) and a higher interrupting capacity at 690 V. If your BOM calls for the 3RV2023-4DA10 but you only need 12.5 A, this unit drops in without rewiring — same terminal spacing, same screw-type connections. Just verify the trip class and current setting match your motor FLA. ## Integration & wiring Screw terminals on the main circuit accept 2x (0.75–2.5 mm²) solid or stranded, or 2x 4 mm². Main contact screws are M3. Torque to the Siemens spec (typically 1.2–1.5 Nm, verify on the nameplate). Operating temperature -20 to +60 °C; storage -50 to +80 °C. The wide voltage range (20–690 V) covers global line voltages without a different variant.","metaTitle":"Siemens 3RV2011-1KA10-ZX95 SIRIUS Motor Protection CB, Class","metaDescription":"Siemens
