Product details

Siemens 3RT5035-1AB00 — SIRIUS Size S2 Power Contactor

Rated for AC-3e duty up to 690 V, this contactor delivers 11.4 kW at 690 V, making it suitable for three-phase induction motor switching in conveyor, pump, and fan applications. The AC-3e maximum switching rate of 1 000 operations per hour matches typical process-cycle demands; for heavier AC-4 plugging or inching duty, the rate drops to 300 operations per hour, which governs service life in reversing or jogging circuits.

Side-by-side mounting is permitted, so multiple contactors can be ganged without spacing gaps — useful for compact motor control centers. Screw-type terminals on both main and auxiliary circuits accept 2x (0.75 to 16 mm²) solid or stranded copper, or 2x (18 to 2 AWG). The product extension for auxiliary switches is supported, so adding a side-mounted block for status feedback or interlocks is straightforward without changing the contactor body.

Compliance documentation covers RoHS and REACH with a substance prohibitance date of 03/01/2017. The insulation voltage rating is 690 V, and the degree of pollution is 3 (conductive pollution typical in industrial environments).

Frequently asked questions

How do I get current pricing and availability for 3RT5035-1AB00?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

When sourcing 3RT5035-1AB00, what's the closest functional second-source — 3RT5035-1AH00?

The 3RT5035-1AH00 is a peer in the same Size S2 frame with the same AC-3e voltage rating and similar dimensions. The key difference is the coil voltage: the 1AB00 uses a 24 V 50 Hz coil, while the 1AH00 uses a different coil voltage. Panel fit is identical — same footprint, same DIN rail mounting — so a swap requires only verifying the control circuit voltage matches the replacement coil.

Will 3RT5035-1AB00 drop into a panel that was specified around 3RT5035-1AH00 without rewiring?

Yes, the physical footprint is identical — both are Size S2 with 55 mm width and 115 mm depth, using the same screw and snap-on DIN rail mounting. No re-drilling or panel modification is needed. The only consideration is the coil voltage: the 1AB00 requires 24 V 50 Hz, so verify the control transformer matches before installing.

What compliance documentation does Siemens provide for 3RT5035-1AB00?

The part complies with RoHS and REACH with a substance prohibitance date of 03/01/2017. The insulation voltage is rated at 690 V, and the degree of pollution is 3 per IEC standards. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
