The best surge protection solutions operate quietly in the background. They provide a reliable, around-the-clock defense against power surge events, giving homeowners and businesses peace of mind that their electronics, appliances, and other connect devices will be protected.

However, not all surge protective devices are created equal. Although competing solutions may look the same on the outside and claim similar levels of protection, it’s what’s inside – and what’s verified by testing – that matters most.

Here’s a look at how Intermatic’s AG3000 Surge Protective Device stands apart from the competition through a superior design and rigorous testing standards.

Tested to a Higher Standard

A surge protective device’s nominal discharge rating reflects its ability to protect connected equipment (e.g., HVAC systems, heat pumps, mini-splits, etc.) from damage caused by power surge events. A higher rating equates to stronger surge endurance and a greater protection margin.

Most manufacturers test their devices to only 10 kA, whereas the Intermatic AG3000 is tested to nominal discharge rating of 20 kA – double the industry standard.

An SPD that’s only rated for 10 kA degrades faster, leading to earlier end-of-life, more frequent replacements, and higher long-term maintenance costs. By investing in an AG3000, customers get superior protection that helps avoid costly repairs over the long haul.

Better Components Provide an Extra Level of Safety

When it comes to internal components and SPD technology, specifics matter. Manufacturers sometimes use inferior components then try to pass it off as new technology. The truth: it’s often just marketing jargon.

The AG3000 uses premium TPMOV® technology (Thermally Protected Metal Oxide Varistor), which provides greater protection than standard MOVs (Metal Oxide Varistors). This thermal protection (a dielectric shield) adds an extra layer of safety by disconnecting when the unit experiences sustained overvoltage or end-of-life conditions. It’s a built-in failsafe.

Additionally, thermal protection should not be confused with being “thermally fused” or having “TFMOV Technology.

Every listed SPD must be thermally fused, so to promote that as a competitive advantage is misleading. It’s akin to advertising that a new car has an innovative new design because it has four wheels – of course it does.

Superior Design, Fast Response Time

Voltage spikes can damage expensive equipment in an instant and response time is critical. However, some manufacturers have a roundabout way of reaching industry standards.

One example of this is when manufacturers use a combination of GDTs (Gas Discharge Tubes) and MOVs instead of higher quality TPMOV technology.

GDTs are slow to react (~100 – 1,000 ns) and are susceptible to follow-current issues. Because of this, SPDs that use GDT components must also incorporate MOV technology in a “hybrid” design just to. It’s not a competitive advantage; it’s out of necessity.

Conversely, the premium TPMOV technology within the AG3000 has a near-instant response time without relying on additional components. It’s a clean, reliable design that’s built to perform over the long haul.
