DPA 3-Phase HVAC Monitoring Relays

Carlo Gavazzi DPA 3-Phase HVAC Monitoring Relays are specially designed for HVAC systems using low-GWP refrigerants. These relays help protect compressors, enable sustainability, and ensure compliance as manufacturers phase out and replace high-GWP HFCs with next-generation refrigerants such as R-32, R-1234yf, and R-290. While these alternatives support climate goals, they also have a higher ignition risk and require strict compliance with IEC/EN 60335-2-40 and UL 60335-2-40 safety standards. Carlo Gavazzi DPA 3-Phase HVAC Monitoring Relays provide a reliable and certified solution, operating completely spark-free while meeting the ignition-free requirements for A2L and A3 refrigerants. The DPA HVAC relays provide continuous phase-sequence and phase-loss monitoring to ensure compressors remain protected from main-grid failures. Ideal applications include commercial and industrial heat pumps, chillers, and rooftop units.
