Product details

The 3RT2035-1CL24-3MA0: The coil terminals are screw-type, and the main contacts are rated for 18 to 1 operations (mechanical life of 10,000,000 cycles typical). It mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° forward/backward tilt.

Switching rates and thermal limits

Maximum switching rates vary by duty: 1,200 operations per hour for AC-1 resistive loads, 1,000/h for AC-3 motor starting, 750/h for AC-2 slip-ring motors, and 300/h for AC-4 plugging/reversing. The arcing time spans 10 to 20 ms, with the coil dropout arcing at 10 to 18 ms.

Dimensions are 114 mm high, 55 mm wide, and 174 mm deep. Wire sizes accepted are 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). No built-in auxiliary switch — if you need aux contacts, they're added separately.

Frequently asked questions

What are the key ratings for this contactor?

The key motor-switching rating (AC-3) is 40 A at 480 V. It also carries a 7.5 hp rating at 230 V. The mechanical life is 10,000,000 operations typical.

What are the mounting and clearance requirements?

It mounts via screw or snap-on onto a 35 mm DIN rail. Clearances needed: 10 mm above, 10 mm below, 10 mm in front, and 6 mm at the sides. Dimensions are 114 x 55 x 174 mm (H x W x D).

Does this contactor include an auxiliary contact block?

No, the auxiliary switch is listed as 'No' — it ships as a bare contactor without built-in aux contacts. You'll need to add an auxiliary contact block separately if required.
