Low-cost Contact Achieves High Current Rating

Tyco Electronics has introduced the KILOVAC brand LEV200 contactor. Capable of carrying 500 A, the contactor is designed for power switching applications in electric and hybrid electric vehicles, forklifts, trains, generators, welding equipment and a host of other systems. With a broad contact voltage rating and a lower cost than other comparably rated contactors, the newly designed LEV200 suits a variety of high-volume applications. Additionally, the hermetically sealed nature of the product makes it intrinsically safe and thus suitable for use in explosive and harsh environments.

The LEV200 has 1 Form X (SPST-NO-DM) main contacts. It is rated to continuously carry 500 A 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 is 12 Vdc up to 900 Vdc. A 1 Form A (SPST-NO) auxiliary contact set rated 2 A at 30 Vdc or 3 A at 125 Vac is available as an option.

Although the LEV200 is not position sensitive when it comes to mounting, designers may select an upright mounting or side-mount attachment style. The low overall height of the side-mount LEV200 makes it suitable for applications with tight space requirements.

Standard coils are available for operation on 12 Vdc, 24 Vdc and 48 Vdc. Models for operation on 96 Vdc and 115 Vac or dc are offered on a special-order basis. Coil termination options include strip leads and #10-32 threaded studs. The KILOVAC LEV200 contactor is priced at $42.05 at the 100-piece quantity level.
