For resistive loads (AC-1), the switching rate reaches 1,200 operations per hour; for AC-3 motor starts, 1,000 ops/h; for AC-4 inching/jogging, 300 ops/h. DC switching capability is covered by DC-13 ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. The contactor's mechanical life is rated at 10 million operations typical, and the dropout time on DC control is 20 to 25 ms with an arcing time of 10 to 15 ms. The 3RT1035-1BD40 occupies a 55 mm wide by 112 mm high by 130 mm deep footprint on the DIN rail. Side-by-side mounting is permitted, so multiple contactors can be ganged without spacing gaps — useful for compact reversing or star-delta assemblies. Wire sizing: the main circuit accepts stranded conductors from 2x (0.75... 25 mm²) and solid or stranded from 2x (0.75... 16 mm²). The control circuit takes solid wire 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), up to max 2x (0.75... 4 mm²). At 40 °C the minimum permissible conductor is 16 mm². The substance prohibition date of 05/01/2012 aligns with RoHS compliance requirements.","metaTitle":"Siemens 3RT1035-1BD40 SIRIUS Power Contactor, S2 Frame, 22 k","metaDescription":"Siemens 3RT1035-1BD40 SIRIUS power contactor, S2 frame size.
