Product details

SIRIUS size S0 power contactor — 24 VAC coil, screw terminals

The coil is rated for 24 VAC at 50/60 Hz, drawing 7.8 VA at 50 Hz and 0.24 A at 60 Hz. Rated operational current at AC-12 is 10 A maximum. The main circuit withstands impulse voltage of 6 kV.

Mounting and integration — DIN rail, side-by-side, vertical rotation

Mounting position allows vertical surface orientation with +/-180° rotation and +/-30° tilt forward/back. Front protection is IP20, terminal area is IP00 — adequate for enclosed panel use; the terminal block itself is not touch-safe when live.

Terminal capacity and wire ranges

Screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). Maximum conductor size for AC-1 rated current is 10 mm². Auxiliary contacts — one NO and one NC — each rated 25 A. Auxiliary circuit impulse withstand is also 6 kV.
