SIRIUS Size S0 Contactor with AC Coil
The Siemens 3RT2326-1AV60 is a SIRIUS-branded Size S0 contactor with an AC-operated magnet coil terminated via screw-type terminals. The coil type and terminal style are the primary differentiators from DC-coil or cage-clamp siblings in the same frame size. Rated for main contact utilization categories AC-3 and AC-4, the contactor's switching capacity is defined by the Size S0 frame — a standard 60 mm wide, 85 mm high, 97 mm deep envelope that fits the 35 mm DIN rail mounting profile per DIN EN 60715. The AC coil draws 10 A at 24 V rated value and 10 A at 230 V rated value, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.28 at 60 Hz. The coil's arcing time is 10 ms, and the mechanical service life is typically 10 million operations.
The 97 mm depth is the dimension from the DIN rail mounting surface to the furthest projection, critical when sizing a shallow enclosure. Main circuit terminals accept 1 to 10 mm² stranded wire; auxiliary terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded. The auxiliary switch is included, with two attachable auxiliary contact blocks possible.
The auxiliary contact ratings span 24 V (10 A) through 690 V (1 A) AC, covering typical control circuit voltages across global panel standards.
