The PC673-1A-TF-48A is a 30 amp SPST NO power relay with flange mounting and 48VAC coil, designed for high-current switching applications. It features Fast-On terminals, dual contacts with T-bar construction, and a dielectric strength of 4000 VAC between coil and contacts. The relay operates with a coil power of 2.5 VA and has an operate and release time of 30 ms maximum. Contact material is silver oxide alloy, with an initial contact resistance of 50 mΩ max. The operating temperature range is -40°C to 85°C, and it meets UL94V-2 flame resistance standards. The maximum switching voltage is 277VAC, with a resistive load rating of 30A at 277VAC. The relay is process sealed and has a mechanical life of 5 × 10⁷ operations and an electrical life of 1 × 10⁵ operations. The case dimensions and terminal strength are consistent with the TF mounting configuration.
