Product details

Side-by-side mounting is allowed, which keeps panel fill factor tight — 55 mm wide per unit. Main circuit and auxiliary/control wiring use screw-type terminals.

This matters when you're fitting the contactor into a gland plate or a tight enclosure corner — you're not locked into one orientation. Operating temperature range is -10 to +55 °C; storage from -25 to +70 °C. For DC-13 loads at 220 V, the contactor switches 0.3 A — useful for DC brake coils or solenoid valves in the same panel. The magnet coil draws 0.78 W closing and 0.42 W holding at DC, so the control transformer sizing is modest.

Frequently asked questions

What is the closest functional second-source — 3RT7036-1AG00?

The 3RT7036-1AG00 is a peer in the same S2 frame size and shares the same DIN footprint, so it drops into the same panel layout. The key difference: the 3RT7035-1AM00 has an AC coil, while the 3RT7036-1AG00 uses DC. Check your control voltage before substituting.

What are the physical dimensions of 3RT7035-1AM00?

Width 55 mm, height 112 mm, depth 115 mm. The 55 mm width is the critical dimension for DIN-rail spacing in multi-contactor panels.

Will 3RT7035-1AM00 drop into a panel specified around 3RT7036-1AG00 without rewiring?

Yes, the mechanical footprint is identical — same S2 frame, same 55 mm width, same DIN-rail mounting. The main power circuit wiring is interchangeable. The only rewire needed is the control circuit if the coil voltage type differs (AC vs DC).

What compliance documentation is available for 3RT7035-1AM00?

The contactor carries an insulation voltage rating of 690 V and surge voltage resistance of 6 kV, meeting IEC 60947-4-1. The IP20 front and IP00 terminal protection ratings are specified. Specific RoHS/REACH/UL declarations are part of the Siemens SIRIUS documentation package available on request.
