With a capability of carrying 500 A, the KILOVAC LEV200 contactor from Tyco Electronics is designed for power switching applications typically found in the switchgear, pitch & yaw drives and generators of wind turbines.
The hermetically sealed construction, with an inert gas in the contact chamber and an epoxy-sealed resin case to provide long-term reliability, make the contactor suitable for use in harsh environments as found in offshore wind farms. Contacts will not oxidize or become contaminated even during long periods of nonoperation. The LEV200 contactor has 1 Form X (SPST-NO-DM) main contacts, with an auxiliary 1 Form A (SPST-NO) contact set available as an option. It is rated to carry 500 A continuously at 320 VDC when using 400 MCM conductors at 65?C. Higher ratings are possible with other conductors. The LEV200 can interrupt up to 2000 A at 320 VDC. Contact voltage rating ranges from 12 VDC to 900 VDC.
