Product details

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.

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. 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.

Frequently asked questions

What is the depth of 3RT2326-1AL20?

The depth is 97 mm.

What is the solid/stranded wiring capacity for 3RT2326-1AL20?

Main circuit accepts 1…10 mm² solid or stranded; auxiliary contacts accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²).

Will 3RT2326-1AL20 drop into a panel specified around 3RT2326-1BK80 without rewiring?

Both share the same Size S0 footprint (85×60×97 mm) and DIN-rail mounting, so the mechanical fit is identical. However, the coil voltage differs — this unit uses 230 V AC, while the 1BK80 variant uses a different coil voltage. Rewiring the coil circuit is required if the panel's control voltage doesn't match.
