Product details

It is rated for 7.5 kW at 400 V in AC-2 duty (slip-ring motors, reversing starts), and carries a maximum AC-12 operating current of 10 A for resistive loads.

Dimensions are 61 mm wide, 85 mm high, 91 mm deep.

Main circuit wiring uses screw-type terminals accepting solid or stranded conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) for the smaller range, and 2x (1...2.5 mm²), 2x (2.5...6 mm²), max 2x 10 mm² for the larger. AWG equivalents are 2x (20...16), 2x (18...14), 1x 12. Pollution degree 3 applies, so the contactor is suited for industrial environments with conductive contamination.

Frequently asked questions

What is the closest functional second-source for the 3RT1325-1AU60?

The 3RT1023-1AL20 is a smaller-frame SIRIUS contactor but does not share the same pole count or rating. The 3RT1325-1AU60 is a 4-pole size S0 contactor; the 3RT1023-1AL20 is a 3-pole size S00. They are not drop-in replacements — panel layout and terminal assignments differ.

What are the key ratings of the 3RT1325-1AU60?

It is a 4-pole power contactor rated 7.5 kW at 400 V AC-2, with a maximum AC-12 operating current of 10 A. Mechanical life is 10 million cycles. It mounts on 35 mm DIN rail and measures 61 x 85 x 91 mm.
