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 1,200 W or 10,000 VA switching power. The OT4 variant features panel mounting with quick-connect terminals and a sealed, non-washable enclosure. It meets UL 508 and UL 873 spacing requirements with 3.18 mm through-air and 6.36 mm surface clearance. The relay has AgCdO contacts, Class F insulation, and operates with a 220 VAC coil consuming 9.1 VA at 86 mA. Must operate and release voltages are 165 VAC and 86 VAC, respectively. Operating temperature range is -55°C to 100°C, with a maximum contact resistance of 30 mΩ at 1 A, 6 VDC. It is RoHS compliant and rated for 1 × 10⁵ electrical operations and 1 × 10⁷ mechanical operations. Weight is 31 grams.
