Coil pulls in at 24 V DC, holds at 3.3 W. Screw terminals on both main and control circuits. ## Not a drop-in for the 3RT2028 frame If your BOM originally specified a 3RT2028-1BB40, this 3RT1016-1BB41 is a different frame size – S00 versus S0 (or S2). The mounting footprint, terminal spacing, and current ratings diverge enough that you can't swap without panel rework. The 3RT2028 family handles higher motor currents; the S00 is for smaller loads up to about 5.5 kW at 690 V. Stick with the correct frame for the job, but if you're sorting a mixed lot, this one moves fast for low-power switching. Screw terminals accept solid or stranded wire: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), up to 2x (0.75–4 mm²) for main contacts. For AWG, that's 2x 20–16, 2x 18–14, 1x 12. Auxiliary contacts take the same gauge. Pollution degree 3, IP20 on front and terminals. Side-by-side mounting permitted, no derating gap needed.","metaTitle":"Siemens 3RT1016-1BB41 SIRIUS Contactor, 24 V DC, 10 A","metaDescription":"Siemens 3RT1016-1BB41 SIRIUS power contactor, Size S00, 24 V DC coil, 10 A auxiliary switching, screw terminals, IP20.
