Any mounting position is allowed, which simplifies layout in a crowded panel. The AC-3 maximum operating voltage is 690 V, with a rated operational voltage range of 20 to 690 V. Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x 1 to 2.5 mm² or 2x 2.5 to 10 mm². The screw terminal uses a Pozidriv size 2 tip with a 5 to 6 mm diameter screwdriver shaft. M4 terminal screws on the main contacts. No ground-fault or phase-failure detection built in — this is a straightforward thermal-magnetic or electronic motor-protective breaker without integral ground-fault sensing.","metaTitle":"Siemens 3RV2321-1BC10-ZX95 SIRIUS Circuit Breaker, 100 kA at","metaDescription":"Siemens SIRIUS 3RV2321-1BC10-ZX95 circuit breaker for starter combinations.
