5-2-1 Surge Protector - FAQs



Is the 5-2-1 Surge Protector UL certified?

Absolutely. 5-2-1 SPD series surge protectors are certified to the latest 1449 3rd edition UL standard (including a certificate number) that can be found on our manual, literature, packaging and UL website.

What is maximum surge current rating for each model?

The SPD60 is rated up to 60,000 amps. The SPD150 is rated up to 100,000 amps.

Why are there two indicator lights?

5-2-1 Surge Protectors have TWO independent LED diagnostic lights, one showing protection present the other showing if the device has power. Our competition typically has only one indicator light which is confusing for the technician and homeowner as you cannot easily tell if the device is working.

What type of equipment is guaranteed protection?

Unlike our competition that only covers air conditioners, 5-2-1 Surge Protectors offers a connected equipment guarantee on any electro-mechanical device connected to the AC power line including the entire HVAC unit, Furnaces, Heat Pumps, Motors and Refrigeration Systems.

How are the 5-2-1 Surge Protectors more advanced than other products?

5-2-1 Surge Protectors are made with the latest MOV technology including patented UL listed MOV parts that have better joule ratings (maximum energy dissipation). In addition, 5-2-1 Surge Protectors have 1 thermal fuse for every MOV part; whereas the competition typically uses only 1 thermal fuse for every TWO MOV parts. By having more thermal fuses our product offers BETTER protection and BETTER compliance to the UL 1449 3rd edition standard.

What is the warranty?

5-2-1 offers a product warranty regardless if you register the product or not for 3 years. Beware, some of competitor's warranties are only valid if you register the product within 15 days after connecting the device.

Is the housing weatherproof?
