The PTRA-OT series is a 40-amp power relay with an AC coil, designed for switching resistive and motor loads up to 277 VAC and 1,200 W or 10,000 VA. It features a panel-mount configuration with quick-connect terminals and mounting tabs for OT4 and OT5 variants, and a low-profile case. The relay meets UL 508 and UL 873 spacing requirements with 3.18 mm air clearance and 6.36 mm surface clearance. It has a 2.0 VA coil power consumption at 12 VAC, operates within a -55°C to 100°C temperature range, and uses AgCdO or AgSnOInO contacts. The device is RoHS compliant and carries UL Class F insulation. Mechanical life is 1 × 10⁷ operations, with electrical life of 1 × 10⁵ operations at 40 A resistive load. Weight is 31 grams.
