Product details

The Siemens 3RT2038-3AB00 is a Size S2 SIRIUS power contactor rated for 65 A at 480 V in AC-3 duty — the rating that governs motor switching out here in the grease. The 24 V 50 Hz coil pulls in reliably, and the spring-type terminals (2x 0.5...2.5 mm² solid or stranded) save panel wiring time over screw clamps.

The 55 mm width and 114 mm height leave room for adjacent devices in a crowded panel.

Auxiliary contacts and environmental range

Built-in auxiliary switch (1 N.O. + 1 N.C.) handles 10 A at 24 V, 2 A at 48/60 V, and 0.3 A at 220 V.

Frequently asked questions

What are the key ratings for 3RT2038-3AB00?

The main motor-switching rating is 65 A at 480 V AC-3. The coil is 24 V 50 Hz. Mechanical life is 10 million cycles typical. Spring-type terminals accept 2x 0.5...2.5 mm².

Where can I buy 3RT2038-3AB00?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3RT2038-3AB00 drop into a panel wired for 3RT2016-2AB02-ZX95?

Both are SIRIUS Size S2 contactors with the same 55 mm width and DIN-rail footprint. The 3RT2038-3AB00 carries a higher AC-3 current rating (65 A vs the smaller 3RT2016 size), so the panel's main power wiring and overload relay must be sized for that higher current. Mechanical fit is the same; electrical coordination needs a check.
