The 9-1617814-6 is a polarized, single-side stable SPDT relay from the FCA-125 series, designed for high-current switching applications. It features a permanent magnet drive for a balanced force mechanism, ensuring high contact pressure and reliable performance in both activated and deactivated states. This relay is rated for a resistive load of 25 Amps at 28 VDC or 115 VAC 400 Hz, with an overload capacity of 50 Amps DC. Built with an all-welded, hermetically sealed construction, it operates over a wide temperature range of -70°C to +125°C and at altitudes up to 300,000 feet. Its robust design, qualified to standards like M6106/19, makes it suitable for demanding aerospace and defense environments.
