As the North American HVAC-R industry transitions towards lower global warming potential (GWP) refrigerants, the demand for components that meet stringent safety and performance criteria has intensified. ZETTLER is proud to announce that its popular AZ2280 series of power relays has successfully passed the rigorous UL 121201 certification, affirming its compliance with the requirements of UL 60335 for applications using A3 refrigerants. This new AZ2280R ignition protected option maintains American ZETTLER as a premier choice for HVAC-R applications including Electrical Heat Pumps, Air-Conditioners, and Dehumidifiers, Refrigerating Appliances, Ice-Cream Appliances, and Ice-Makers.
Previously already certified as IP67 and for A2L refrigerants under UL’s LZGH category, the AZ2280R’s new certificate under UL’s NCKL ensures its suitability for use in Class I, Division 2, and Class III hazardous locations, simplifying customer’s product evaluations to UL 60335 requirements. With its long proven design and adherence to the latest safety standards, ZETTLER continues to lead the way in delivering innovative and compliant solutions for the evolving HVAC-R market.

ZETTLER Group North America is pleased to announce that we will be moving operations to below address in Vista, California.
This positive trend is also evident in associated sales of charging infrastructure solutions. In particular, wall charging stations – so-called “wallboxes” – that enable EV charging with AC voltage according to charging mode 3 (IEC 61851-1) are and will continue to be in extraordinary demand. They facilitate charging of electric vehicles with voltages up to 400V, and are used in protected areas such as parking garages, carports or private homes.
For the switching of 600VAC-800VAC circuits, large contactors have traditionally been the only viable option but new high capacity relays from ZETTLER are challenging those assumptions.
