Product details

Rated operating current hits 65 A at 480 V — that's the AC-3 motor-switching current, so it handles a 3-phase induction motor up to roughly 40 hp at 480 V without derating. Screw-type coil terminals and main contacts make it a straightforward drop-in for existing panel wiring.

The 55 mm width and 114 mm height fit standard panel layout grids. That keeps the arc space and cooling path clear without over-allocating panel real estate.

The headline number — 65 A at 480 V — is the AC-3 rated operating current, meaning it switches three-phase squirrel-cage motors up to that current under full load. For resistive loads (AC-1), the switching frequency can go to 700 operations per hour; for AC-3 motor duty, 500 ops/h; for AC-4 (plugging/reversing), 150 ops/h. The coil draws 0.36 A at 50 Hz and 0.39 A at 60 Hz — standard control transformer sizing. Auxiliary switch is built in, rated 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V. That covers most PLC output and relay interposing needs without an add-on block.

Frequently asked questions

What is the depth of 3RT2038-1AN20?

130 mm depth, 55 mm width, 114 mm height. That's the body size; add clearance per the mounting spec (10 mm upwards, forwards, downwards; 6 mm at the side).

Where can I buy 3RT2038-1AN20?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time — no stock count or lead-time number published here.

What compliance documentation does Siemens provide for 3RT2038-1AN20?

Standard Siemens SIRIUS documentation package includes RoHS and REACH declarations, plus IEC/EN 60947-4-1 compliance. UL and CSA listings are typical for this series, though specific cert numbers should be confirmed from the unit marking or Siemens support portal.
