Product details

SIRIUS Power Contactor, 110 V DC Coil, Spring-Terminal

It carries a 52 A rated operational current at both 480 V and 600 V, and is rated for 10 hp motor loads at 230 V.

Ratings and Application Context

The 110 V DC coil draws a 1.5 A inrush peak and holds with a dropout ratio of 0.7 of rated value. The spring-type terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire, reducing wiring time compared to screw terminals. Auxiliary contact ratings span from 10 A at 24 V DC down to 0.3 A at 220 V DC, covering pilot duty and PLC input signaling. The main contacts are configured as 3 normally open (3NO) with one normally closed (1NC) auxiliary, per the 18...1 designation.

Frequently asked questions

What are the key ratings of the 3RT2036-3XF40-0LA2?

It is a size S2 power contactor with a 110 V DC coil, rated 52 A at 480 V and 600 V, and 10 hp at 230 V. It includes spring-type terminals and an auxiliary switch.

Where can I buy the 3RT2036-3XF40-0LA2?

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

What is the depth of this contactor?

The depth is 130 mm, with a width of 55 mm and height of 114 mm.

Will the 3RT2036-3XF40-0LA2 drop into a panel specified for a 3RT2036-1AC20-ZX95?

Both are size S2 SIRIUS contactors sharing the same DIN rail footprint and mounting hole pattern, so mechanical fit is identical. The main difference is the coil voltage — this unit has a 110 V DC coil versus the other variant's coil — so verify coil supply before swapping.
