Product details

Physical fit and rail footprint

The 3RT2035-3AK60: This is a Size S2 contactor — 55 mm wide on the DIN rail, 114 mm tall, 130 mm deep.

What the 40 A rating means for the motor load

The headline number for this contactor is 40 A at 480 V in AC-3 duty — that's the current it can switch across the main contacts for a standard squirrel-cage motor start/run profile.

Termination and wiring reality

The magnet coil and main contacts terminate with spring-type terminals — no screw torque to check, just strip and push. The auxiliary switch is built in, so you don't need a separate side-mount block for basic feedback.
