Rated control supply voltage is 200-220 V AC, with a pick-up threshold of 0.8 times rated value and a drop-out threshold of 0.9 times rated value at both 50 Hz and 60 Hz.
Dimensions are 214 mm high, 160 mm wide, 225 mm deep — the 225 mm depth is the critical panel clearance dimension for enclosure depth selection. Main circuit power connections accept stranded conductors from 70 to 240 mm² — sized for the high-current bus work this frame class handles. Auxiliary contact wiring uses screw-type terminals on the magnet coil, accepting 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or max 2x (0.75-4 mm²) solid or stranded conductors.
Switching performance and lifecycle
Maximum switching rates: 750 operations per hour at AC-3 and AC-3e duty (motor starting), 700/h at AC-1 (resistive), and 250/h at AC-2 and AC-4 (high-inrush or plugging duty).
Sourcing and fit considerations
This is a vacuum contactor, not an air-break design — the sealed vacuum chamber eliminates contact oxidation and pitting, which is the key difference from standard SIRIUS contactors in the same frame size. The 200-220 V AC coil is specific to this variant; verify control voltage compatibility before specifying into a panel with 230 V or 240 V control transformers.
