At 24 V the coil draws 10 A inrush, settling to a lower hold current. The contactor is rated for side-by-side mounting without derating, which saves rail space in dense panels. The main circuit uses screw-type terminals, accepting 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 wire. That covers standard motor and control wiring without needing special ferrules or bootlace ends. The auxiliary circuit also carries a rated impulse voltage of 6 kV, matching the main circuit for coordinated insulation in 400 V line-fed panels. Mechanical life is typical at 30 million operations, so it suits high-cycle applications like conveyor sortation or packaging lines. Dimensions are 45 mm wide, 57.5 mm high, and 72 mm deep — a compact footprint that fits standard 45 mm-wide DIN-rail slots. The mounting position allows vertical surface mounting with +/-180° rotation and +/-30° tilt front-to-back, giving flexibility in tight enclosures. Side clearance of 6 mm is required at the side for arc flash containment.","metaTitle":"Siemens 3RT1516-1BD40 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1516-1BD40 power contactor, Size S00, 24 VDC coil rated 10 A.

The 3RT1516-1BD40 is a direct 24 VDC coil variant; swapping to an AC-rated coil may require circuit changes. Verify coil compatibility before substituting."},{"question":"What is the depth of 3RT1516-1BD40?","answer":"The depth is 72 mm from the mounting surface to the front of the contactor."},{"question":"What wire sizes does the 3RT1516-1BD40 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 conductors."},{"question":"Will 3RT1516-1BD40 drop into a panel specified for 3RT1015-1BB42 without rewiring?","answer":"Both are Size S00 contactors with the same DIN-rail footprint and screw terminal layout, so mechanical fit is the same. However, the coil voltage and power differ — 3RT1516-1BD40 is 24 VDC only, while 3RT1015-1BB42 is 24 VAC/DC. If the panel supplies 24 VAC, the DC coil may not hold in. Rewiring the coil supply to DC is required."},{"question":"What compliance documentation does Siemens provide for 3RT1516-1BD40?","answer":"Siemens provides a declaration of conformity for IEC/EN 60947-4-1, CE marking, and RoHS compliance.
