The PTRA-OT series is a 40-amp power PCB relay with AC coil operation, designed for resistive and motor loads up to 277 VAC. It features two contact forms (1A or 1C), with OT3 variant providing 1 Form C contacts and combining PCB and QC terminals. The relay complies with UL 508 and UL 873 spacing requirements, has Class F insulation, AgCdO contact material, and is RoHS compliant. It operates at 277 VAC with a rated coil power of 7.2 VA, 207.75 mA coil current, and a 10 ms release time. The device has a maximum switching power of 10,000 VA, contacts rated at 40 A resistive, and operates within a temperature range of -55°C to 100°C. The OT3 model mounts on a printed circuit board with alternate pinout and is process sealed.
