With a capability of carrying 500 A, the KILOVAC LEV200 contactor from TE Connectivity is designed for power switching applications typically found in the switchgear, pitch and 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, makes the contactor suitable for use in harsh environments as found in offshore wind farms. Contacts will not oxidise or become contaminated even during long periods of non-operation.
The LEV200 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 V d.c. 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 V d.c. Contact voltage rating ranges from 12 V d.c. to 900 V d.c.
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 V d.c., with 96 V d.c. and 115 V a.c. or d.c. offered on a special-order basis. Coil termination options include strip leads and 10-32 threaded studs.
