The 2-1611750-5 is a single-pole power relay from the 9400 series, engineered for extensive use in HVAC applications with flexible mounting options that do not affect operation. It features silver alloy power contacts rated at 12 FLA and 60 LRA at 125VAC, with maximum ratings of 18A at 125VAC resistive and 8 FLA at 240/277VAC, along with fine silver pilot contacts rated at 3A at 277VAC. The relay operates with coil voltages ranging from 12 and 24 VDC to 6-277 VAC at 50/60 Hz, with a maximum sealed power consumption of 4 VA for AC coils and 3 W for DC coils, and maintains continuous duty cycle operation. It incorporates convenient 0.250" (6.35 mm) quick connect terminals for easy installation and features an operating temperature range of -40°C to +65°C with UL Class B insulation (130°C). This relay is ideal for applications requiring reliable switching in HVAC systems, industrial controls, and other environments where multi-positional mounting flexibility and robust contact performance are essential.
