Siemens 3RT2025-1AN10 SIRIUS Power Contactor — Size S0, 480 V 14 A
It carries a 14 A rating at 480 V in AC-3 duty (motor switching) and 3 hp at 230 V, making it a fit for small to mid-range three-phase motors on 480 V or 230 V lines. Mounting is via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, and the contactor can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward — useful when fitting into tight enclosures or existing layouts. The S0 frame width is 45 mm, so it occupies a single DIN-rail module position.
The 3 hp at 230 V rating gives a direct match for common 230 V single-phase or three-phase motor sizes. For DC switching, the contactor has a rated operating current curve: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. These are the values for breaking DC inductive loads — the arcing time is 10 ms, and the switching frequency for AC-4 duty (plugging/inching) is limited to 300 cycles per hour.
Depth fits standard enclosures with wiring clearance. These are the minimum air gaps to maintain for arc flash and heat dissipation — important when packing multiple contactors on a DIN rail.
