SIRIUS Power Contactor 3RT2046-1AG20 — Integrator Notes
It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and the +/-180° rotation on a vertical surface plus +/-22.5° tilt flexibility simplifies panel layout in tight enclosures. Rated switching frequencies vary by duty: AC-1 (resistive) at 900 cycles/h, AC-3 (motor start/run) at 850 cycles/h, AC-4 (plugging/inching) at 250 cycles/h. The AC-3e rating also sits at 850 cycles/h — the same as AC-3, so for standard motor applications you get full throughput without derating. The screw-type main contact terminals accept solid conductors 2.5...16 mm² and stranded 6...70 mm², covering most motor feeder sizes up to the S3 frame capacity. Auxiliary contacts are included, wired via 2x (0.5...1.5 mm²) solid or stranded. Operating temperature range -25...+60 °C, storage -55...+80 °C, making it suitable for unheated electrical rooms or outdoor cabinets with climate control.
No end-of-life notice or successor has been issued.
Dimensions: 140 mm height, 70 mm width, 152 mm depth. These clearances are for arc flash and heat dissipation — respect them in the panel layout.
