Product details

SIRIUS S0 power contactor, 45 mm wide

The Siemens 3RT2025-4AK60 is a SIRIUS-branded power contactor in the S0 frame size, designed for screw and snap-on mounting onto 35 mm standard mounting rail per DIN EN 60715. Its 45 mm width fits standard DIN-rail panel layouts, and the S0 frame supports typical motor switching and resistive loads up to the rated AC-3 duty cycle of 1 000 operations per hour.

The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward and backward by +/- 22.5° on a vertical mounting surface, giving flexibility in tight enclosures. Minimum clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side.

Environmental and auxiliary specs

Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. Arcing time is 10 to 10 ms at AC.

Frequently asked questions

Where can I buy 3RT2025-4AK60?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the width and depth of 3RT2025-4AK60?

The contactor has a width of 45 mm and a depth of 97 mm, fitting standard DIN-rail panel layouts.

Will 3RT2025-4AK60 drop into a panel specified around 3RT2036-1AC20-ZX95?

Both are SIRIUS S0 frame contactors with the same 45 mm width and DIN-rail mounting, so the 3RT2025-4AK60 can physically replace a 3RT2036-1AC20-ZX95 without rewiring, provided the coil voltage and load ratings match the application.
