If you are considering Intermatic IG1240RC3 to protect your entire house against power surges and spikes, you are in the right place. Glowing reviews of this whole house surge suppressor from Intermatic can be found on major online retail platforms.

Intermatic IG1240RC3 Whole Home Type-1 or 2 Surge Protection Device

Intermatic IG1240RC3 offers individual component thermal protection and monitoring in addition to its Type 1 and Type 2 protection capabilities.

Hence it is highly versatile and can be used across both residential and commercial applications. A single component failure will turn the LED indicator off so that necessary replacement can be planned.

What impressed me about this Intermatic surge protection unit is the fact that it comes with an “All Mode” protection feature that offers protection for all conductors in your home electrical system.

It does not matter where you install it. It offers protection for all possible types of power irregularities, distinctively for line-to-line, line-to-neutral, line-to-ground, neutral-to-ground protection paths.

If your home has energy-intensive appliances like HVAC systems, refrigerators, and washing machines, the IG1240RC3 can protect its internal circuits from power fluctuations.

Individuals with high-value electronic setups, such as home theaters, gaming systems, and smart home devices, should consider the IG1240RC3. It shields expensive equipment from sudden power surges.

Who Shouldn’t Intermatic IG1240RC3?

For obvious reasons, if you require something more robust and have a bigger budget, do get one with higher specifications. Surge suppressors like Eaton CHSPT2ULTRA or Siemens FS140. might be to your liking. You may want to read their review for Eaton CHSPT2ULTRA and Siemen FS140.
