Product details

The 3RT2035-1AP64: Rated 40 A at 480 V in AC-3 duty — the standard category for squirrel-cage motor switching under load. These limits govern the thermal load on the arc chamber; exceeding them accelerates contact erosion and reduces the 10 million-cycle mechanical life. Arcing time spans 10 to 20 ms, with a closing time of 10 to 18 ms at rated coil voltage. The contactor is sized for motor starting duty, not continuous resistive loads — AC-1 maximum rate is 1,200 cycles/h, reflecting the lower arc energy when switching resistive circuits.

Panel fit and mounting constraints

Size S2 frame: 55 mm wide, 114 mm high, 174 mm deep.
