The PTRA-OT series is a 40 Amp power PCB relay with AC coil, designed for switching resistive and motor loads up to 277 VAC. It features two mounting variants: OT3 provides 1 Form C (SPDT) contacts with PCB and QC terminals, and is sealed. The relay has AgCdO or AgSnOInO contacts, a maximum switching current of 40 A, and complies with UL 508 and UL 873 spacing requirements. It meets UL Class F insulation standards, operates from -55°C to 100°C, and is RoHS compliant. The 120 VAC coil requires 90 mA at 36 VA, with a must operate voltage of 156 VAC and must release voltage of 36 VAC. Terminal strength is rated at 10 N, and the relay weighs 31 grams.
