TE Connectivity Power Relays, Over 2 Amps FCA-212-BY3

The FCA-212 series is a double-pole, double-throw, electrically held relay with 12-amp contact rating, hermetically sealed and constructed with silver cadmium oxide contacts gold-plated for reliability. It features a permanent magnet drive, balanced force design, and operates continuously from -70°C to +125°C. The relay supports DC coil voltages of 6, 12, 28, 48, and 115 V with AC options at 50/400 Hz. Enclosures include Y-type with socket pins, gold-plated circuit pins, and polarizing pins. It meets dielectric strength of 1250 Vrms at sea level and 350 Vrms at 80,000 feet. Contact make bounce is 1 millisecond at nominal voltage, with a maximum contact drop of 0.175 V at end of life. The FCA-212-BY3 variant uses socket pins with a Y enclosure and a 28 VDC coil.
