Product details

It carries a 24 VDC coil with screw-type terminals and mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 60715.

The mounting position is flexible — ±180° rotation on a vertical surface, and can be tilted forward/backward ±22.5° on a vertical surface. That means it fits into tight panel layouts without worrying about orientation. Dimensions: 85 mm high, 45 mm wide, 141 mm deep. The 45 mm width is a standard 2.5 module width on a DIN rail — leaves room for adjacent devices. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. Keep those gaps for heat dissipation and arc flash clearance.

Operating conditions

Rated for operation from -25 °C to +60 °C, storage from -55 °C to +80 °C.

Frequently asked questions

Where can I buy the 3RT2025-1AK64 and how is it quoted?

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

What is the 3RT2025-1AK64's depth?

Listed depth is 141 mm.

What solid wire range does the 3RT2025-1AK64 accept?

Solid wire range is 1 to 10 mm².

Will the 3RT2025-1AK64 drop into a panel specified for the 3RT2036-1AC20-ZX95 without rewiring?

Both are size S0 contactors with screw terminals and snap onto 35 mm DIN rail, so the footprint and mounting are the same. However, the 3RT2036-1AC20-ZX95 is a different variant — verify coil voltage and auxiliary contact configuration against your BOM before swapping.
