The PTRA-OT series is a 40-amp power PCB relay with an AC coil, designed for resistive and motor loads up to 277 VAC. It features a low-profile case with PCB pins and quick-connect terminals, available in 1-form A (SPST-NO) and 1-form C (SPDT) configurations. The relay meets UL 508 and UL 873 spacing requirements with 3.18 mm air clearance and 6.36 mm surface clearance. It has AgCdO or AgSnOInO contact material, Class F insulation, and is RoHS compliant. The coil operates at 277 VAC with a rated power consumption of 7.2 VA and a maximum operating temperature of 100°C. The part is sealed and has a mechanical life of 1 × 10⁷ operations and an electrical life of 1 × 10⁵ operations under resistive load. Physical dimensions and mounting style are consistent across variants with PCB and QC terminals.
