SIRIUS 3RT2036-1AV04 — Power Contactor for Motor and Resistive Loads
The Siemens SIRIUS 3RT2036-1AV04 is a size S2 power contactor rated for 52 A at 480 V, suited for switching motor loads in AC-3 duty up to 800 operations per hour, or resistive loads in AC-1 duty up to 1 000 operations per hour. Its coil draws 6 A at 24 V rated value, with a pickup time of 10 to 18 ms and an arcing time of 10 to 20 ms. The contactor mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and its operating temperature range is -25 to +60 °C.
DIN-Rail Integration and Panel Fit
At 55 mm wide and 114 mm high, the 3RT2036-1AV04 fits standard DIN-rail enclosures. Depth is 174 mm, so verify gland-plate clearance — especially if the panel has a shallow back door or rear-mounted busbars. The contactor can be rotated ±180° on a vertical mounting surface and tilted forward/backward ±22.5°, which helps when routing power wiring around adjacent devices. Minimum air gaps: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm to the side.
