The PTRA-OT series is a 40 amp power relay with AC coil operation, designed for switching resistive and motor loads up to 277 VAC and 40 A. The OT4 variant, used in this part, 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 air clearance and 6.36 mm surface creepage. The relay has AgCdO contacts, Class F insulation, and is RoHS compliant. It operates with a 24 VAC coil, drawing 7.2 VA at 180 mA, with a must operate voltage of 18 VAC and a must release voltage of 7.2 VAC. Terminal strength is 10 N, and the operating temperature range is -55°C to 100°C. The relay achieves 1 × 10⁵ electrical operations at 240 VAC resistive load and 1 × 10⁷ mechanical operations. Weight is 31 grams.
