The detection circuit catches that condition and trips before winding damage sets in. The 55 mm width fits a standard 3-module footprint on the rail, leaving room alongside a contactor for a compact motor starter assembly. Depth is 149 mm, so verify clearance to the backplane or enclosure door — some shallow 200 mm deep enclosures will need the breaker mounted on a sub-panel or rail offset. Terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper. Main contact screw size is M6.","metaTitle":"Siemens 3RV2032-4EA15 SIRIUS Motor Protection CB, 50 kA","metaDescription":"Siemens 3RV2032-4EA15 SIRIUS motor protection circuit breaker.
