Product details

It carries a 24 VDC coil and is rated for a 10 A operational current at 24 V (AC-12), with an AC-4 rating of 8.5 A at 400 V for reversing or inching duty.

The 10 A rating at 24 V (AC-12) covers resistive and transformer loads at that voltage. The AC-2 rating of 4 kW at 400 V applies to slip-ring motor starting. The mechanical life of 30,000,000 cycles tells you the contactor is built for high-cycle applications like conveyor or packaging lines.

The IP20 protection on the front and terminals means it's finger-safe inside an enclosure but not washdown-rated.

Screw 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 or stranded conductors. These are the values to specify when designing the branch circuit protection.

Frequently asked questions

What is the closest functional alternative to 3RT1016-1AQ05?

The 3RT1016-2AP02 is a peer in the same S00 frame size but uses a 24 VAC/DC coil with spring-cage terminals instead of screw-type. If your panel is wired for screw terminals, the 3RT1016-1AQ05 is the direct fit; swapping to the -2AP02 would require re-terminating the control wiring.

What are the key ratings for this contactor?

Rated operational current 10 A at 24 V (AC-12), AC-4 rating 8.5 A at 400 V, AC-2 rating 4 kW at 400 V. Coil is 24 VDC. Mechanical life 30,000,000 cycles.

What compliance documentation is available for this part?

The part carries CE marking for the European market and is designed to IEC 60947-4-1. RoHS and REACH declarations are standard for Siemens SIRIUS products. UL/CSA listings are typical for the series but should be confirmed per the specific catalog number.

Will 3RT1016-1AQ05 drop into a panel specified for 3RT1016-2AP02?

The mounting footprint (45 mm width, DIN rail) and main circuit ratings are identical. The difference is the terminal type: screw-type on the -1AQ05 versus spring-cage on the -2AP02. If the panel wiring uses ferrules or bare wire, the screw terminals are compatible; if the existing wiring is terminated with spring-cage-specific ferrules, no change is needed.
