Product details

The Siemens 3RT1016-1AH01 is a SIRIUS power contactor in the Size S00 frame, rated for 4 kW at AC-2 duty on 400 V three-phase. The 24 VDC coil pulls in at the standard 0.8 x Us and holds across the full operating range.

The IP20 finger-safe front terminals mean no additional shrouding inside a closed panel.

Compared to the 3RT1016-1AR11 (which carries a 110 VAC coil), the 1AH01 is the 24 VDC variant. Same Size S00 frame, same 45 mm width, same 4 kW AC-2 rating. The swap is a coil-voltage decision only — if your control voltage is 24 VDC, this is the one; if you're on 110 VAC, the 1AR11 drops in without rewiring the power circuit.

Frequently asked questions

Where can I buy 3RT1016-1AH01?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is the closest functional second-source for 3RT1016-1AH01?

The 3RT1016-1AR11 is the same Size S00 power contactor with identical 4 kW AC-2 rating, but with a 110 VAC coil instead of 24 VDC. It drops into the same panel footprint without rewiring the main circuit.

What is the depth of 3RT1016-1AH01?

72 mm deep, 45 mm wide, 57.5 mm tall — fits a standard DIN-rail module slot with side-by-side mounting allowed.

What wire sizes does 3RT1016-1AH01 accept?

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) stranded. AWG equivalents: 2x (20 to 16), 2x (18 to 14), 1x 12.
