SIRIUS 3RT5036-1AG00 — Size S2 Power Contactor
Footprint is 55 mm wide by 115 mm deep by 112 mm tall, so it takes up a standard four-module-wide slot on the DIN rail. The screw-and-snap-on mounting fits 35 mm rail per DIN EN 50022, and you can rotate it ±180° on a vertical surface or tilt it ±22.5° forward and back — handy when you're squeezing it into a tight enclosure. That puts it solidly in the 400 V and 690 V motor control world. At 60 °C ambient it still delivers 22 kW at 230 V, 38 kW at 400 V, and 66 kW at 690 V — so no derating headache in a warm cabinet.
Terminals and Wiring
Main and auxiliary/control circuits both use screw-type terminals. The main terminals accept 2x (0.75…16 mm²) solid or stranded, or 2x (18…2 AWG). That's enough for 80 A fuse protection (gL/gG) on the main circuit — a common choice for this size contactor. Minimum wire size at 40 °C and 60 °C is 16 mm² — that's the same for both, so you don't need to upsize for a hotter panel.
Operating Conditions
Electrical switching rates: 5,000 cycles per hour at AC, up to 1,000/h at AC-1, 800/h at AC-3, and 300/h at AC-4 — so it handles frequent starting and stopping without issue.
