The Kilovac EV100 contactor from TE Connectivity (NYSE: TEL) offers hermetically sealed construction for safe operation in explosive or harsh environments. Rated for 100 A at 600 Vdc, the contactor uses an inert gas in the contact chamber and an epoxy-sealed resin case to provide long-term reliability. Contacts will not oxidize or become contaminated during long periods of nonoperation. Isolation of 8 kVdc across the open contacts permits use for high-voltage isolation.
Designed in accordance with AS 9100 requirements, EV100 contactors are suited for ground power applications in aerospace as well as industrial and commercial power distribution, circuit isolation, automotive battery switching, and backup. Other applications include inverter control and battery switching in alternative energy applications such as wind and solar power.
The compact package, available in a bottom-mount configuration occupying less than 4 cubic inches and weighing only 4.4 oz, is not position sensitive, which allows flexible application, according to TE. The contactor features a coil economizer to reduce power consumption, with a coil operating voltage range of 9 to 36 Vdc. Standard coil termination is 15-inch flying leads. Contact configuration is SPST-NO-DM (Form X).
