Product details

The S0 form factor (55 mm wide, 85.5 mm tall, 91 mm deep) fits standard panel layouts.

The AC-3 motor-switching rating governs the real-world load: this contactor handles induction motors up to the current limit defined by the motor's locked-rotor and running duty cycle. For DC-13 solenoid loads at 220 V, the rated operational current is 0.3 A — relevant for brake coils or holding magnets in the same panel.

Environmental and protection class

IP20 on the front and at the terminals — finger-safe against accidental contact but not sealed against moisture or dust ingress. Operating temperature range -10 to +55 °C; storage range -25 to +70 °C.

Wiring and auxiliary options

Main and auxiliary/control circuits use screw-type terminals. Accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or finely stranded wire with core-end processing. The product accepts auxiliary switch add-ons (product extension auxiliary switch: Yes), so a side-mount block can be fitted for feedback or status indication without replacing the contactor.

Short-circuit protection coordination

For type 1 coordination, the maximum fuse rating is 63 A gL/gG NH 3NA. For type 2 coordination (where the contactor must remain operational after a fault), the fuse limit drops to 25 A gL/gG NH 3NA. This distinction matters when selecting upstream protection for a motor branch circuit that must survive a short-circuit event without contactor replacement.

Frequently asked questions

Where can I buy 3RT7025-1AM05 and how do I get a price?

The 3RT7025-1AM05 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time commitment.

What is 3RT7025-1AM05's listed depth?

The depth is 91 mm.

What is 3RT7025-1AM05's listed width?

The width is 55 mm.

Will 3RT7025-1AM05 drop into a panel specified around 3RT6026-1AN20 without rewiring?

Both are S0-size contactors on the same 35 mm DIN-rail standard, so the footprint and mounting rail are identical. Terminal type (screw) and wire range (0.5–2.5 mm²) are the same. A drop-in swap is mechanically and electrically feasible without panel rework, provided the coil voltage matches the control circuit.

What compliance documentation does Siemens provide for 3RT7025-1AM05?

Standard Siemens SIRIUS documentation includes a CE declaration of conformity, UL/CSA file listings, and RoHS/REACH compliance declarations. The part carries a rated insulation voltage of 690 V and surge voltage resistance of 6 kV, which supports IEC 60947-4-1 compliance for contactors.
