The Siemens SIRIUS 3RT2026-1NP30-ZX95 is a size S0 power contactor with a 200 … 280 V AC coil, screw-type terminals, and an integrated auxiliary switch. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, making it a direct panel fit for standard control cabinets. The coil draws an inrush peak of 25 A, so verify your control transformer sizing — that's the instant the contactor pulls in, not the hold-in current.
Mounting & Integration
Fastening method is screw and snap-on onto 35 mm DIN rail per DIN EN 60715. Mounting position allows ±180° rotation on a vertical surface, plus ±22.5° forward/backward tilt — handy when you're squeezing into a crowded panel and need to orient the contactor for wire routing. The S0 frame keeps width to 45 mm, depth 107 mm, height 85 mm. Clearances: 10 mm upwards, forwards, and downwards; 6 mm at the side. Stranded or solid wire from 1 to 10 mm² on the main contacts.
Switching Performance & Duty
Rated for AC-3 duty (motor switching) at up to 750 operations per hour; AC-4 (plugging/inching) at 250 ops/h. Arcing time is a tight 10 ms, and the coil operates across 200 … 280 V AC. Ambient range during operation is -25 … +60 °C; storage from -55 … +80 °C. The auxiliary switch is built in — no separate add-on needed for feedback or status indication.
