Power switching in a compact package

Also referred to as power relays, these relays are designed for consistent high contact pressure, with lower bounce and less arching to help extend contact life. These relays range from the compact 5 amp package up to a 50 amp version in a 1-inch cube enclosure. Our mid-range relays are available in a variety of coil options that allow AC or DC control and in many terminal styles that include socket pins, solder pins, and solder hooks. Each series also come with a variety of mounting options. The mid-range line is qualified to MIL-PRF-6106 and MIL-PRF-83536 for severe condition applications. Our relays offer a balanced force design that provides critical size and weight savings to contacts. These relays are typically hermetically sealed and commonly used in aircraft and rotorcraft applications.

FCA-150 Series Relay

Single-Pole, Electrically Held, 50 Amps or Less

The FCA-150 series relay is a polarized, single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state. This results in appreciably increased contact pressure in both states over that of a spring return non-polar design. 1 Form X (SPST-NO-DM) configuration with main contacts rated 50 Amps.
