SIRIUS 3RT2526-2NF30 — Size S0 Contactor, Spring-Terminal Coil
The Siemens SIRIUS 3RT2526-2NF30 is a Size S0 contactor with a coil rated 95...130 V AC/DC and spring-type terminals on the magnet coil. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, fitting a 61 mm wide DIN slot. The 107 mm depth leaves clearance for gland plates and adjacent devices in a standard 200 mm deep enclosure. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C.
Switching Ratings and Coil Inrush
Coil inrush peaks at 15 A, then holds at the rated value. At 24 V DC the contactor switches 10 A; at 48 V and 60 V DC it switches 2 A; at 110 V DC it switches 1 A; at 125 V DC it switches 0.9 A; at 220 V DC it switches 0.3 A; at 230 V AC it switches 10 A; at 400 V AC it switches 3 A; at 440 V AC it switches 1 A. The arcing time is 10 ms, and the operating time (both AC and DC) is 30 to 50 ms. Mechanical life is 10 million operations typical.
Mounting and Clearances
Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. Required clearances: 0 mm upwards, forwards, backwards, and downwards; 6 mm at the side. The spring-type coil terminal accepts 2x (0.5 to 2.5 mm²) solid or stranded wire. The auxiliary switch is included.
