FBR611D012-K is a single-pole K-type power relay designed for high-capacity switching applications. It features a 12 VDC nominal coil voltage with 285 O coil resistance and 42 mA nominal current, delivering maximum switching capacity of 16 A at 240 VAC and 30 VDC. The relay incorporates silver-cadmium oxide contacts with a contact resistance of maximum 100 mO at 1 A 6 VDC, and provides 5 kV AC minimum dielectric strength between coil and contacts with 10 kV surge strength. Operating over a temperature range of -40°C to +70°C with mechanical life rated at 20 × 106 operations minimum and electrical life of 1 × 106 operations minimum at contact rating, this relay meets UL 508 safety standards. The K-type configuration enables enhanced switching performance suitable for industrial control, automation systems, and power distribution applications requiring reliable high-current switching.
