Surge Protector

Intermatic AG3000 Surge Protector – HVAC Surge Protective Device (120/240VAC, 20kA, Type 4X)

Protect valuable HVAC equipment and home appliances from damaging power surges with the Intermatic AG3000 Surge Protective Device (SPD). Designed specifically for HVAC systems, the AG3000 helps prevent costly breakdowns caused by lightning strikes, utility grid fluctuations, and internal power surges — the silent threats that can shorten equipment life or cause sudden failure.

Unlike standard surge protectors, the AG3000 uses advanced TPMOV (Thermally Protected Metal Oxide Varistor) technology, which eliminates the hazardous failure modes often associated with traditional MOV components. This state-of-the-art protection makes it a trusted choice for contractors and homeowners looking to safeguard air conditioners, heat pumps, and other high-value equipment.

Installation is quick and straightforward, making it an ideal add-on for new or existing HVAC systems. A bright green LED indicator provides clear, at-a-glance confirmation that protection is active, giving peace of mind that your system remains defended.

Built for durability, the AG3000 features a Type 4X watertight and UV-resistant enclosure, allowing it to withstand harsh outdoor conditions while delivering reliable performance year-round.
