Product details

S2 frame size and DIN rail fit

The 3RT2036-3AF00: Depth is 130 mm, so budget that clearance behind the panel door or enclosure backplate.

Motor switching current — 52 A at 480 V

The headline motor rating is 52 A at 480 V (AC-3 duty) — that is the current it can switch inductive motor loads under typical starting conditions. The magnet coil uses spring-type terminals (push-in or cage-clamp style), which speeds wiring compared to screw terminals — no torquing, just strip and insert.
