Product details

SIRIUS Size S2 power contactor — the 65 A at 480 V rating sets the load boundary

The Siemens 3RT2038-3AK64-3MA0 is a SIRIUS Size S2 power contactor rated 65 A at 480 V, which means it can switch motor or resistive loads up to that current at 480 V AC — a common industrial voltage for 3-phase equipment.

The contactor is rated for 500 operations per hour at AC-3 (motor switching) and AC-3e, and 700 ops/h at AC-1 resistive load. If your application cycles faster than that — say a rapid reversing conveyor — you need to stay within these limits to avoid contact welding.

Clearance and mounting position — panel integration constraints

The contactor measures 55 mm wide, 114 mm high, and 178 mm deep.

Frequently asked questions

What are the key ratings for this contactor?
