What this contactor relay is and what it does
The Siemens 3RT2627-1NF35 is a SIRIUS contactor relay with a 95-130 V AC/DC coil, screw-type terminals, and a 45 mm width that fits standard 35 mm DIN rail per DIN EN 50022. It switches loads across a range of voltages: 6 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, with a maximum operating rate of 100 switching cycles per hour up to 600 V, dropping to 72 cycles per hour at 690 V. The coil holds across the 95-130 V range at 50/60 Hz, with a pickup ratio of 0.7 to 1.3 times rated value.
Where it lives in the panel
Mounts via screw or snap-on onto 35 mm DIN rail. The 45 mm width means it takes up one standard 45 mm module slot in a control panel. Mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° on a vertical surface — useful when panel layout is tight. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
Terminal capacity and wiring
Screw-type terminals accept solid conductors: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or 2x 4 mm². Stranded conductors: 2x (1-2.5 mm²) or 2x (2.5-10 mm²). At 40 °C ambient, a single 10 mm² conductor is rated; at 60 °C, two 10 mm² conductors. The coil terminals are screw-type as well.
