Product details

SIRIUS S2 Power Contactor — 3RT1034-1AG20-ZW95

Rated for 50/60 Hz operation, the contactor handles AC-3 duty at 400 V up to 15 kW and AC-1 resistive loads up to 1200 operations per hour. The S2 frame keeps the width at 55 mm — tight enough for high-density panel layouts with side-by-side mounting permitted.

Terminal & Wiring

Main circuit terminals accept solid conductors from 2x 0.5 mm² up to 2x 4 mm², and stranded conductors from 2x 0.75 mm² up to 2x 25 mm². The screw-type clamp is standard for panel wiring — no special tooling required. Auxiliary and coil connections share the same terminal family, keeping the wiring kit consistent across the panel.

Environmental & Mounting

Mounting is screw-and-snap onto 35 mm DIN rail.

Frequently asked questions

What is the closest functional second-source to 3RT1034-1AG20-ZW95?

The 3RT5034-1BW40 is a peer in the same S2 frame class, but it uses spring-cage terminals instead of screw-type. If your panel wiring is already terminated with screw clamps, the 3RT1034-1AG20-ZW95 is the direct fit — no re-termination needed.

Where can I buy 3RT1034-1AG20-ZW95?

This part is sourced and quoted to order against an RFQ through independent industrial distribution. Availability and current pricing are confirmed at quote time.

Will 3RT1034-1AG20-ZW95 drop into a panel specified around 3RT5034-1BW40?

Both are S2 frame contactors with the same 55 mm width and snap-on DIN rail mounting, so the mechanical footprint is identical. The difference is terminal type: screw-type on this part versus spring-cage on the 3RT5034. If your panel uses screw terminals, this is a direct drop-in.
