Product details

It snaps onto a 35 mm DIN rail per EN 50022, and the spring-type terminals accept solid or stranded wire from 0.5 to 4 mm². The main contacts are rated 20-12 A, and the contactor handles AC-4 duty up to 250 operations per hour.

Coil and switching behaviour

The DC coil picks up at 0.7 times the rated voltage and drops out at 1.25 times, giving a clean pull-in and release. Switching time at DC is 25-45 ms, and arcing time runs 10-15 ms. Inrush current peaks at 1.1 A, so the control transformer or DC supply needs to handle that momentary load without sagging.

Dimensions are 45 mm wide, 70 mm high, 73 mm deep.

Switching capacity across voltages

The contactor's rated operational current varies with voltage and duty. At 24 V DC it handles 10 A; at 48 V and 60 V it drops to 2 A; at 110 V it's 1 A; at 125 V it's 0.9 A; at 220 V it's 0.3 A; at 230 V it's rated 0.75 hp; at 400 V it's 3 A; at 480 V it's 4.8 A; at 500 V it's 2 A; at 600 V it's 6.1 A. These numbers define the load it can switch in a given circuit voltage — match the column that fits your application.

Frequently asked questions

Where can I buy 3RT2015-2XF42-0LA2 and how do I get a price?

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

What is 3RT2015-2XF42-0LA2's listed depth?

The depth is 73 mm.

What wire sizes does the spring-type terminal accept?

The spring-type terminals accept solid wire: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), and 2x 4 mm²; also solid or stranded 2x (0.5-4 mm²).

Will 3RT2015-2XF42-0LA2 drop into a panel specified around 3RT2015-2HB41 without rewiring?

Both are size S00 contactors with the same DIN-rail footprint and similar terminal layout, so the mechanical fit is the same. The main difference is the coil: this one is 72-125 V DC with spring-type terminals, while the 3RT2015-2HB41 uses a different coil voltage and terminal type. If the coil voltage and terminal style match your panel wiring, it will drop in without rewiring.
