SIRIUS Size S0 contactor, 230 V AC coil
The Siemens 3RT2326-1AL20 is a SIRIUS contactor in Size S0, carrying a 230 V AC 50/60 Hz coil with screw-type terminals. It fastens via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° forward/backward tilt — useful when the gland plate or busbar layout forces an unconventional orientation. Operating range is -25 to +60 °C; storage range is -55 to +80 °C.
Panel fit and wiring
Footprint is 85 mm high × 60 mm wide × 97 mm deep — a compact S0 envelope that leaves room alongside other DIN-rail devices for a multi-contactor motor starter group. Clearance: 10 mm upwards, 10 mm downwards, 6 mm at the side. Main-circuit wiring accepts solid or stranded conductors from 1 to 10 mm²; auxiliary contacts take 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²).
Switching ratings and auxiliary contacts
Auxiliary switch is built in. Arcing time is 10…10 ms. Mechanical service life typical is 10,000,000 operations.
