The PTRA-OT series is a 40 Amp power PCB relay with AC coil operation, designed for resistive and motor loads up to 2 HP at 250 VAC and 277 VAC. It features AgCdO or AgSnOInO contacts, a maximum switching voltage of 300 VAC and 110 VDC, and operates with 2.0 VA coil power at 240 VAC. The OT2 variant includes PCB and QC terminals with a dust cover, and the part meets UL 508 and UL 873 spacing requirements of 3.18 mm through air and 6.36 mm over surface. It has a Class F insulation rating, operates from -55°C to 100°C, and is RoHS compliant. The relay has a mechanical life of 1 × 10⁷ operations and an electrical life of 1 × 10⁵ operations under rated load. Termination is in alternate PCB pinout configuration with mechanical dimensions of 0.8 mm pin size for both coil and power pins.
