Product details

SIRIUS S0 power contactor — 3RT2023-4AK60

Panel fit: 45 mm wide, 85 mm high, 97 mm deep. Side clearance to adjacent devices is 6 mm; forward and upward clearance 10 mm.

Rated for 1000 switching cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty; AC-4 max is 300 cycles/h. That 1000 cycles/h covers most motor-starting and resistive-load applications; AC-4 (plugging/inching) is the limiting case. Auxiliary contact switching capacity (24 V rated value: 10 A; 48 V: 2 A; 60 V: 2 A; 110 V: 1 A; 125 V: 0.9 A; 220 V: 0.3 A; 400 V: 3 A; 440 V: 0.6 A; 480 V: 7.6 A; 500 V: 2 A). These are the make/break ratings for the built-in auxiliary switch — use them for control-circuit isolation, not main power. Mechanical endurance typical: 10 million operations. Coil connection is ring cable lug.

Frequently asked questions

How do I get current pricing and availability for 3RT2023-4AK60?

Submit an RFQ through this listing. We source and quote to order against your BOM line; current pricing and availability are confirmed at quote time.

What is 3RT2023-4AK60's listed depth (97 mm) on this component line?

The listed depth is 97 mm.

What is 3RT2023-4AK60's listed width (45 mm) on this component line?

The listed width is 45 mm.

Will 3RT2023-4AK60 drop into a panel that was specified around 3RT2015-4AP62 without rewiring?

Both are SIRIUS S0 contactors with the same mounting footprint (35 mm DIN rail, screw/snap-on), same width (45 mm), same depth (97 mm), and same height (85 mm). The 3RT2023-4AK60 carries an integrated auxiliary switch; the 3RT2015-4AP62 may not. Check your control circuit's auxiliary contact count before swapping.

What compliance documentation does this brand provide for 3RT2023-4AK60 (RoHS, REACH, UL, IEC)?

As a Siemens SIRIUS product, this contactor is designed to meet IEC/EN standards (DIN EN 60715 mounting rail). For specific RoHS/REACH/UL declarations, request the manufacturer's compliance documentation at quote time.
