Product details

Siemens SIRIUS 3RT1034-1AP00-ZW98 — Size S2 Power Contactor

Rated for 50 Hz operation, the contactor delivers 18.5 kW at 500 V and 10 kW at 690 V. In AC-3 duty (motor starting under load), it's rated for up to 1,000 operations per hour; AC-4 (plugging/reversing) drops to 250 ops/h. AC-4 at 400 V is rated at 29 A — that's the inching or jogging current limit, not continuous motor current. The main current circuit uses screw-type terminals, accepting solid conductors up to 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²), and stranded up to 2x (0.75–25 mm²). Keep the panel door interlocked or use finger-safe shrouds if maintenance access is live.

The contactor occupies a 55 mm wide DIN-rail footprint (Size S2), with a depth of 115 mm and height of 112 mm. Side-by-side mounting is supported. AC-1 allows 1,200 ops/h, AC-3 1,000 ops/h, AC-4 250 ops/h.

Frequently asked questions

What is the closest functional second-source for 3RT1034-1AP00-ZW98?

The 3RT5034-1BW40 is a Size S2 contactor in the same SIRIUS family, but it's a 3RT5 generation part with different coil ratings and auxiliary configurations. The 3RT1034-1AP00-ZW98 is a 3RT1 generation part. They are not drop-in interchangeable without verifying coil voltage, terminal layout, and accessory compatibility. For a direct replacement, stick with the same order code or consult Siemens cross-reference documentation.

What are the key dimensions of 3RT1034-1AP00-ZW98?

The contactor measures 115 mm depth, 55 mm width, and 112 mm height. It mounts on a 35 mm DIN rail per EN 50022 with screw and snap-on fastening.

What wire sizes does the 3RT1034-1AP00-ZW98 accept?

Solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²). Stranded: 2x (0.75–25 mm²). Solid or stranded: 2x (0.75–16 mm²). All connections use screw-type terminals on the main current circuit.

Will 3RT1034-1AP00-ZW98 drop into a panel specified for 3RT5034-1BW40?

No, not without verification. The 3RT1034 is a 3RT1 generation contactor; the 3RT5034 is a 3RT5 generation. While both are Size S2, differences in coil rating, auxiliary contact arrangement, and terminal layout mean they are not direct mechanical or electrical substitutes. Check the panel wiring diagram and Siemens compatibility notes before substitution.
