The PTRA-OT series is a 40-amp power relay with an AC coil, designed for switching resistive and motor loads up to 277 VAC. It features a low-profile case with PCB pins and quick-connect terminals for OT2 variants, and meets UL 508 and UL 873 spacing requirements with 3.18 mm air gap and 6.36 mm surface creepage. The relay uses AgCdO contacts, has a maximum switching current of 40 A, operates with a 240 VAC coil requiring 72 VAC release and 312 VAC maximum, and consumes 8.3 VA. Insulation is Class F, and it is RoHS compliant. The OT2 variant has PCB pins and a sealed enclosure. Operating temperature range is -55°C to 100°C, with a mechanical life of 1 × 10⁷ operations and electrical life of 1 × 10⁵ operations at rated load. Weight is 31 grams.
