The magnetic short-circuit release is fixed at 65 A (the N release), so it clears hard faults upstream of the motor starter. Clearance distances are 20 mm upwards and downwards, 9 mm to the side, and 0 mm forwards and backwards — meaning you can butt it against the back panel or adjacent devices without extra spacing on those faces. ## Integration note Size S00 is the smallest frame in the SIRIUS 3RV1 family — 45 mm wide, 75 mm deep, 90 mm high. It snaps onto the same 35 mm DIN rail as contactors and overload relays, and Siemens publishes a combination table for direct mounting with S00 contactors (e.g., 3RT2 series) without additional wiring between the breaker and contactor. The power loss at rated current is 7.25 W total (2.4 W per pole), so no special ventilation is needed in a standard IP20 enclosure. The breaker is designed for motor protection per IEC 60947-2 and -4, with thermal overload and magnetic short-circuit release built in — no separate overload relay needed for the motor branch.","metaTitle":"Siemens 3RV1011-1FA10-ZI45 SIRIUS Circuit Breaker, 5 A, CLAS","metaDescription":"Siemens SIRIUS 3RV1011-1FA10-ZI45 motor protection circuit breaker, size S00, 3.5...5 A adjustable overload, CLASS 10 trip, screw terminals.
