The 45 mm width means it takes up one standard 45 mm module slot — no surprises in a crowded panel. Height is 90 mm and depth is 81 mm, with 0 mm clearance needed at the back or sides. That zero-clearance spec means you can butt it against other devices on the rail without worrying about heat buildup or arc flash gaps. Wiring is all spring-loaded terminals — both the main circuit and the auxiliary/control circuit. Solid conductors from 0.25 to 2.5 mm² or finely stranded with ferrule from 0.25 to 1.5 mm². AWG equivalents are 24 to 14 for the main contacts. The front is IP20 finger-safe and touch protection is rated finger-safe, so it's safe to work around live in a locked panel.","metaTitle":"Siemens 3RV1011-0FA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-0FA20-ZX95 motor protection circuit breaker, 0.5 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.

The 0GA10 has a higher current rating, so the swap depends on whether the downstream motor is sized for 0.5 A.
