Product details

Rated AC-2 at 400 V for 18.5 kW — that's the slip-ring motor duty, where starting current stays moderate. AC-4 at 400 V is 35 A, covering plugging and inching cycles. AC-1 resistive load maxes at 1200 operations per hour, AC-3 at 1000, AC-4 at 300. The coil holds at 24 VDC nominal (10 A), drops out below 18 V. RoHS compliance date is May 1, 2012.

Side-by-side mounting is allowed — no gap needed. Main circuit terminals accept solid 2x (0.25...2.5 mm²) or stranded 2x (0.75...25 mm²). The 55 mm width and 112 mm height fit standard panel layouts.

Frequently asked questions

How do I get current pricing and availability for 3RT1035-3AD00?

Submit an RFQ; the part is sourced through independent distribution and pricing is confirmed at quote time.

What is the closest functional second-source for 3RT1035-3AD00?

The 3RT1026-1AB00 is a smaller SIRIUS contactor (size S0) with lower ratings — it will not drop into the same panel without rewiring and checking the load current. The 3RT5035-1AH00 is a higher-rated SIRIUS contactor with different terminal layout. Neither is a direct swap.

What compliance documentation does Siemens provide for 3RT1035-3AD00?

RoHS compliance is documented with a substance prohibition date of May 1, 2012. The part is designed for pollution degree 3 environments.
