With a capability of carrying 500A, 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 degrees 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.
Available in styles for upright mounting or side mounting, mounting of the LEV200 is not position sensitive. The low overall height of the side-mount configuration makes it particularly suitable for applications with tight space requirements.
Standard coils are available for operation on 12, 24 and 48 VDC, with 96 VDC and 115 VAC or DC offered on a special-order basis. Coil termination options include strip leads and 10-32 threaded studs.
