Product details

It switches motor loads up to 52 A at 480 V, making it a fit for 30–50 hp 480 V three-phase motors in conveyor, pump, and fan duty.

Switching duty and mechanical life

Rated for 1 000 cycles/hour at AC-1 (resistive), 800 at AC-3 and AC-3e (standard motor start/run), and 250 at AC-4 (plugging/inching). If your application hits AC-4 regularly, derate the switching frequency accordingly — the 250 c/h ceiling is the mechanical limit for that duty, not a suggestion.

Panel integration and clearances

Dimensions: 55 mm wide, 114 mm tall, 130 mm deep. That 6 mm side clearance is tight — if you're grouping several S2 contactors side by side, account for the cumulative gap when laying out the DIN rail. Auxiliary switch block is fitted (18–1 configuration, meaning one N/O + one N/C built in). Wire terminations accept 2x 0.5–1.5 mm² or 2x 0.75–2.5 mm² solid/stranded, screw terminals on the coil side.

Frequently asked questions

Will 3RT2036-1AL20-ZX95 drop into a panel designed for 3RT2037-1AL20-ZX95 without rewiring?

The 3RT2037 is a larger frame size (S3 vs S2). The 3RT2036-1AL20-ZX95 is physically smaller — same DIN rail pitch but shorter depth and lower current rating. It will not replace the 3RT2037 without a panel re-layout and cable re-rating.

What is the depth of 3RT2036-1AL20-ZX95?

130 mm. That depth includes the contactor body only; add clearance for wiring and the auxiliary switch block if fitted.
