The 1-1617807-3 is a 25 Ampere, 3PDT relay from the FCA-325 series, designed for reliable switching in harsh environments. It features a polarized, single-side stable design with a permanent magnet drive, which results in increased contact pressure. This relay operates with a nominal 28 VDC coil voltage and has a DC resistance of 290 Ω. Its all-welded, hermetically sealed construction, silver cadmium oxide contacts with gold plating, and an operating temperature range of -70°C to +125°C ensure high reliability. Qualified to M83536/32 and /33, it is ideal for power distribution, motor control, and lighting systems in aerospace and defense applications.
