For AC-4 reversing or inching duty at 400 V, the rated operational current is 8.5 A, which is the figure to use when the contactor sees frequent plugging or jogging. The DC coil draws 3.3 W during both pick-up and hold, which simplifies the control transformer sizing — no spike at pull-in to account for. The pick-up threshold is 85% of rated voltage (20.4 V for a 24 V coil), and the drop-out is 1.1× rated (26.4 V), so the contactor stays latched through a sag but drops cleanly on overvoltage. Main circuit terminals accept 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or up to 2× (0.75 to 4 mm²) solid or stranded copper. For AWG, that translates to 2× (20 to 16), 2× (18 to 14), or 1× 12. Screw-type terminals — no spring-cage here, so factor in the extra torque-check step during panel build. For Type 1 coordination (device may be damaged but no fire hazard), use gL/gG 35 A.","metaTitle":"Siemens 3RT1016-1BB42-ZW95 SIRIUS Power Contactor, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1016-1BB42-ZW95 power contactor, size S00, 24 VDC coil, 10 A rated operational current.

The 3RT1016-1BB42-ZW95 carries a higher AC-12 current rating (10 A vs the 3RT1015's lower rating), so the swap depends on whether your load fits within the smaller contactor's curve. Both share the same S00 frame footprint and terminal layout, so no rewiring is needed for a drop-in replacement if the current fits."},{"question":"What is the depth of the 3RT1016-1BB42-ZW95?","answer":"72 mm. Combined with the 45 mm width and 57.5 mm height, it occupies a compact S00 footprint on the DIN rail."},{"question":"What wire sizes does the 3RT1016-1BB42-ZW95 accept?","answer":"The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded.
