Vacuum Contactors
The Vacuum Contactor HR‐VS is an electromechanically operated device determined for frequent switching of exclusively alternating current circuits with voltage up to 1200V according to EN 60947‐1 and EN 60947‐4‐1 with currents of up to 630A in the range of closing and breaking currents corresponding to AC4 category. This contractor is used particularly for switching of squirrel cage and slip‐ring motors. It is suitable for switching of resistance and mixed loads.
Technical merits
- High-reliability,
- long lifetime,
- minimum maintenance demanded during its whole lifetime,
- high frequency of repeated switches,
- small size and low weight.
