Product details

The Siemens 3RT7035-1AG20 is a size S2, 3-pole contactor from the SIRIUS family, rated for AC-3 switching duty up to 690 V. That 690 V AC-3 ceiling means it handles motor loads at common 400 V and 480 V line voltages with headroom for 690 V systems — the insulation voltage matches at 690 V, so no derating for voltage stress.

Mounting & Panel Fit

The 55 mm width and 115 mm depth fit standard S2 contactor footprints — side-by-side mounting is permitted, so multiple units pack tightly on the rail.

Coordination & Protection

For type 2 coordination, the required upstream fuse is a gL/gG NH 3NA: 80 A; for type 1 coordination, 125 A. Shock resistance is rated at 15g / 5 ms and 8g / 10 ms sine pulse — robust for machine-mounted applications.

Frequently asked questions

Where can I buy 3RT7035-1AG20 and how do I get a price?

The 3RT7035-1AG20 is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing.

What is 3RT7035-1AG20's listed depth (115 mm) on this component line?

The listed depth is 115 mm, with a width of 55 mm and height of 112 mm, fitting the standard S2 contactor footprint.

Will 3RT7035-1AG20 drop into a panel that was specified around 3RT5036-1AP00 without rewiring?

Both are S2-size contactors with similar DIN-rail mounting and screw terminals, so the 3RT7035-1AG20 should physically fit the same footprint. However, verify the coil voltage and auxiliary contact arrangement against your specific 3RT5036-1AP00 wiring before committing — the evidence does not confirm identical coil specs.

What compliance documentation does this brand provide for 3RT7035-1AG20 (RoHS, REACH, UL, IEC)?

The evidence does not list specific compliance certifications for this order code. For RoHS, REACH, UL, or IEC documentation, request the manufacturer's declaration from the supplier at quote time.
