Product details

SIRIUS S2 power contactor, 65 A AC-3 — what fits

The Siemens 3RT2038-3AF00 is a SIRIUS S2 power contactor rated 65 A at 480 V in AC-3 duty — that's the motor-switching current, not the resistive load. AC-3 covers starting and running of squirrel-cage motors, so this contactor handles a 65 A motor load at that voltage. The S2 frame size (114 mm high, 55 mm wide, 130 mm deep) mounts via screw fixing or snaps onto a 35 mm DIN rail per DIN EN 60715. Coil termination is spring-type.

Switching ratings and operating limits

The contactor's arcing time spans 10 to 20 ms, with an operate time of 10 to 18 ms at AC. Maximum switching frequency varies by duty: 700 cycles/hour at AC-1 (resistive), 500 at AC-3 (motor start/run), 350 at AC-2, and 150 at AC-4 (plugging/inching). The auxiliary switch is included. Mechanical life is typical at 10 million operations.

The spring-type coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire.

Frequently asked questions

What is the AC-3 current rating of 3RT2038-3AF00?

The AC-3 rating is 65 A at 480 V — that's the motor-switching current for starting and running squirrel-cage induction motors at that voltage level.

Can 3RT2038-3AF00 be mounted on a DIN rail?

Yes, it supports screw fixing and snap-on mounting onto a 35 mm standard mounting rail per DIN EN 60715.
