SIRIUS Vacuum Contactor, S10 Frame — Key Ratings and Fit
The rated control supply voltage is 500 to 550 V AC, with a coil of the screw-type terminal variety. The main circuit accepts stranded conductors from 70 to 240 mm², sized for the S10 frame's current-carrying capacity. Mechanical life is typical 10,000,000 operations. Maximum operating frequency depends on duty: 750 cycles/hour for AC-1 and AC-3e, 250 cycles/hour for AC-2 and AC-4. Auxiliary switch is present, with DC rated values: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. The auxiliary terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²).
Mounting position flexibility allows installation on vertical surfaces with ±22.5° rotation and tilt, or standing on a horizontal surface.
Physical Dimensions and Termination
Dimensions: height 210 mm, width 145 mm, depth 206 mm. Fastening via screw fixing through one hole of 11 mm diameter. The main circuit accepts stranded conductors 70 to 240 mm²; auxiliary terminals handle the smaller cross-sections listed above.
