The HCR-1 Series is a mechanical relay with a DPDT contact configuration, rated for 30 A at 277 VAC, designed for general-purpose switching in applications such as HVAC, standby power, and water/wastewater systems. It features .250" (6.35 mm) quick-connect terminals for both power and coil connections, a chassis-mount design, and an operating temperature range of -40 °C to 65 °C. The relay has a coil voltage of 24 VAC, with a nominal coil power of 4 VA, and complies with UL 60947-4-1, CSA C22.2, UL 60335-2-40, and RoHS 2011/65/EU standards. The unit weighs 3.04 oz and has an insulation system rated for Class F (155 °C).
Relays control circuits through a low-power signal. An electro-magnetic current actuates the relay, creating a closed circuit within the device. General purpose relays are used in applications including HVAC systems, food & beverage, standby power supplies and water/wastewater. We carry extensive inventory to meet delivery schedules.
