For direct-on-line motor starting (AC-3), the contactor achieves 1 000 operating cycles per hour; for the harsher AC-4 duty, the maximum is 250 cycles per hour. At 500 V the contactor is rated for 18.5 kW; at 690 V for 10 kW — these higher-voltage ratings matter for 500 V or 690 V line supplies common in mining, marine, or heavy industrial installations. RoHS compliance date is 05/01/2012 (substance prohibitance per EU RoHS). Dimensions: 112 mm height, 55 mm width, 115 mm depth. The S2 frame fits standard 35 mm DIN rail; side-by-side mounting is permitted, saving panel width when multiple contactors are ganged. Main circuit terminals accept 2x (0.75... 25 mm²) stranded or 2x (0.25... 2.5 mm²) solid conductors. At 40 °C the minimum permissible conductor size is 16 mm² for the main circuit — this is a thermal derating consideration for continuous high-current applications. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — these cover typical PLC-level control signals and relay interposing.","metaTitle":"Siemens 3RT1034-3AB00-ZX95 SIRIUS Power Contactor, 15 kW AC-","metaDescription":"Siemens 3RT1034-3AB00-ZX95 SIRIUS S2 power contactor. 15 kW AC-2 at 400 V, 29 A AC-4.
