The PTRA-OT series is a 40 A power PCB relay with AC coil operation, designed for resistive and motor loads up to 277 VAC and 10,000 VA. It features a panel-mount design with quick-connect terminals and mounting tabs for OT4 and OT5 variants, and meets UL 508 and UL 873 spacing requirements of 3.18 mm through air and 6.36 mm over surface. The relay has a 31 g weight, operates from -55°C to 100°C, and uses AgCdO contacts with Class F insulation. The 24 VAC coil requires 7.2 VA power, with a must-operate voltage of 18 VAC and must-release voltage of 7.2 VAC. It is RoHS compliant and rated for 1 × 10⁵ electrical operations. The PTRA-1C-24S-OT5-X matches the OT5 variant with sealed enclosure and single-pole double-throw contact form.
