The 15 operations per hour max at AC-3 tells you this isn't for frequent jogging — it's a branch-circuit protector, not a switching device. Zero clearance needed at the sides or back — you can pack these tight on the rail. The IP20 front means it's finger-safe once installed in an enclosure; the terminals are screw-type with box terminals for the main circuit and separate screw terminals for the aux/control circuit. Wire sizes: solid up to 2x 16 mm², stranded up to 2x 50 mm² (or 1x 70 mm²). That's heavy enough for the 40 A feed. The auxiliary switch option is built in — you can add a signal contact for remote status without extra enclosure space.","metaTitle":"Siemens 3RV1341-4FC10 SIRIUS Circuit Breaker, 40 A, 50 kA","metaDescription":"Siemens SIRIUS 3RV1341-4FC10 circuit breaker for starter combinations. 40 A continuous, 50 kA breaking at 400 V AC, 18.5 kW motor rating.
