The PTRA-OT series is a 40-amp power PCB relay with an AC coil, designed for switching resistive and motor loads up to 277 VAC. It features two mounting variants: OT2 and OT3 with PCB pins and quick-connect terminals, and OT4 and OT5 with mounting tabs and quick-connect terminals only. The PTRA-1A-110CT-OT2-X variant uses a 110 VAC coil with a rated power consumption of 2.0 VA, operates within a temperature range of -55°C to 100°C, and has a 30 mΩ maximum contact resistance at 1 A, 6 VDC. It meets UL 508 and UL 873 spacing requirements, has UL Class F insulation, and is RoHS compliant. The contact material is AgCdO unless specified otherwise; this part uses AgSnOInO. Mechanical life is 1 × 10⁷ operations, electrical life is 1 × 10⁵ operations for resistive loads at 240 VAC, and the device weighs 31 grams.
