The PTRA-T series is a 40-amp, AC-coil power relay for resistive and motor loads up to 277 VAC. Available in T2 (1 Form A) and T3 (1 Form C) variants with PCB and QC terminals, it features AgCdO or AgSnOInO contacts, Class F insulation, and RoHS compliance. It meets UL 508 and UL 873 spacing requirements of 3.18 mm air gap and 6.36 mm surface creepage. The 24 VAC coil consumes 7.2 VA, operates at 18 VAC minimum, and releases at 7.2 VAC. The relay is rated for 1 × 10^5 electrical operations and 1 × 10^7 mechanical operations, with an initial contact resistance of 30 mΩ max. It is epoxy sealed to IP67 and weighs 31 grams. Operating temperature is -55°C to 100°C.
