Product details

Panel Integration & Mounting

Its 70 mm width and 152 mm depth fit standard enclosure layouts, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° forward/backward tilt, giving panel builders flexibility in tight gland-plate arrangements.

Termination & Wiring

The magnet coil uses screw-type terminals. Power circuit wiring accepts stranded conductors: 2x (6…16 mm²), 2x (10…50 mm²), or 1x (10…70 mm²). Auxiliary and control wiring takes solid or stranded 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²). An auxiliary switch is included.

Switching Performance & Clearances

Arcing time is 10…20 ms, and at AC-1 maximum the contactor can handle 900 switching operations per hour. Minimum clearances: 10 mm upwards, 10 mm downwards, 10 mm at the side, 0 mm forwards, 0 mm backwards. Coil pick-up at AC is 11…21 ms.

Frequently asked questions

What are the key dimensions of the 3RT2544-1AP60?

The contactor measures 70 mm wide, 140 mm high, and 152 mm deep, fitting standard Size S3 enclosure cutouts.

What wire sizes does the 3RT2544-1AP60 accept?

Power terminals accept stranded conductors from 6 mm² up to 70 mm² (single). Control/auxiliary terminals accept 0.5…2.5 mm² solid or stranded wire.
