Product details

The Siemens SIRIUS 3RT1016-1HB42 is a size S00 power contactor with a 24 VDC coil, screw-type terminals on both main and auxiliary circuits, and a 45 mm wide footprint that snaps onto 35 mm DIN rail per DIN EN 50022. Its AC-2 rating at 400 V is 4 kW, covering slip-ring motor switching; the AC-4 rating at 400 V is 8.5 A for reversing or inching duty. For resistive loads (AC-12) it carries 10 A.

Wire range for main and auxiliary terminals accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded, plus AWG equivalents 2x (20 to 16), 2x (18 to 14), or 1x 12. That covers most control and small power circuits without lug adapters.

For type 1 coordination (contactor may need replacement after fault), use gL/gG 35 A.

Frequently asked questions

What is 3RT1016-1HB42's listed depth?

The depth is 72 mm.

What wire sizes does it accept?

Main and auxiliary terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded, plus AWG equivalents 2x (20 to 16), 2x (18 to 14), or 1x 12.

Will 3RT1016-1HB42 drop into a panel specified around 3RT1015-1BB42?

Yes, both are size S00 with the same 45 mm width and snap onto 35 mm DIN rail. The terminal layout and screw-type connections are identical, so no rewiring is needed if the control voltage is 24 VDC and the load current is within the 3RT1016's higher ratings.
