Its breaking capacity is the headline: 100 kA at both 240 V and 400 V AC, dropping to 30 kA at 500 V and 12 kA at 690 V. Mounting position is any orientation; the IP20 front face keeps fingers out during commissioning. Main circuit terminals are screw-type with box terminals. Solid conductors accept 2x 2.5 to 16 mm²; stranded goes up to 2x 10 to 50 mm² or 1x 10 to 70 mm². That range covers most motor feeder cables from 4 mm² up to 35 mm² without adapters. Auxiliary and control circuits use separate screw terminals, and the unit supports an auxiliary switch add-on (product extension auxiliary switch: Yes). RoHS compliance date is July 1, 2006, covering the EU RoHS directive. Surge voltage resistance is rated at 6,000 V, and the unit is finger-safe for touch protection.","metaTitle":"Siemens 3RV1342-4AC10 SIRIUS Circuit Breaker, 16 A, 100 kA S","metaDescription":"Siemens SIRIUS 3RV1342-4AC10 circuit breaker for starter combinations. 16 A continuous, 100 kA at 400 V AC, 690 V rated.
