Product: RSH Series
Description: Designed specifically for HVACR equipment, these products are permanently-installed and will protect all single-phase, 120/240-V air conditioning, heat pump, and ductless mini split systems from transient over-voltage and natural-cause surges. The UL 1449 listed products come in two models — the RSH-50 protects from up to 50,000-amp single surges and up to 10,000-amp repetitive surges, and the RSH-60 protects from up to 60,000-amp single surges and 20,000-amp repetitive surges. These products use thermally-fused metal oxide varistors (TFMOVs) combined with a gas discharge tube. The TFMOVs handle the everyday workload of commonly occurring surges generated within the building by millisecond transient over-voltages, in addition to supply-side utility voltage load transfers that repetitively degrade compressor motors, circuit boards, and other electrical components. The gas discharge tube safeguards against TFMOV failures from large catastrophic spikes that can occur from large utility invariances and potential occurrences of lightning-generated electric field damage. Both models use diagnostic LED lights.
