Product details

Mounting and Integration — DIN Rail and Panel Fit

Its dimensions — 55 mm wide, 85.5 mm high, 91 mm deep — fit the standard S0 footprint, so it occupies the same panel space as other S0 contactors. Side-by-side mounting is permitted, which helps when packing multiple contactors on a rail.

For the main circuit, the contactor is rated at AC-3 (motor switching) up to 690 V. The auxiliary and control circuits use screw-type terminals. For type of coordination 2, the required backup fuse is a gL/gG NH 3NA rated 25 A; for type of coordination 1, it is 63 A. The coil's closing power at DC is 0.82 W, holding at 0.24 W. The contactor is rated for 800 switching cycles per hour at AC-3 maximum, and 250 at AC-4.

Environmental and Protection

Shock resistance is rated at 12.5g / 5 ms and 7.8g / 10 ms.

Frequently asked questions

What is 3RT7025-1AG05's listed depth (91 mm) on this component line?

The depth is 91 mm, which is standard for the S0 frame size. Combined with a width of 55 mm and height of 85.5 mm, it fits the same panel cutout as other S0 contactors.

Will 3RT7025-1AG05 drop into a panel that was specified around 3RT6028-1AB00 without rewiring?

Both are S0 frame contactors with the same DIN-rail mounting and similar terminal layouts, so the mechanical fit is the same. However, the 3RT7025-1AG05 uses screw terminals for both main and control circuits, while the 3RT6028-1AB00 may differ in coil voltage or auxiliary contact configuration — verify the coil rating and aux contact count before swapping.

Where can I buy 3RT7025-1AG05 and how is it quoted?

This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.
