Brand: Intermatic | Manufacturer Part Number: AG3000 | Big Frog Supply SKU: AG3000
Product Overview
The Intermatic AG3000 is a hard-wired surge protective device designed for 120/240 VAC single-phase HVAC equipment, distribution panels, and service-entrance applications. It can be installed as a Type 1 or Type 2 surge protector in an approved electrical system and provides three modes of protection across line-to-neutral and line-to-line connections. The device uses TPMOV surge protection technology and is rated for a maximum surge current of 50 kA per phase.
Two status indicators make the protection condition easier to check during routine service. A green light indicates normal operation, while a red indication means protection has diminished and the unit should be replaced. The UV-resistant, watertight Type 4X plastic enclosure supports properly installed indoor or outdoor applications. The AG3000 is a protective component only; it cannot eliminate every possible electrical event and must be installed with the correct conductor routing, overcurrent protection, grounding, and equipment connections.
