Intermatic IG2240-IMSK Whole Home Surge Protector - Easy Module

In this review the Intermatic IG2240-IMSK is presented as a practical whole-home surge protector for homeowners and small business operators who want reliable, serviceable protection. The single biggest reason to consider this unit is its replaceable IModules with LED indicators, which make ongoing maintenance straightforward and fast without replacing the entire SPD. Installers and property owners will appreciate the clear status lights and the Module Power Switch that simplifies safe replacement of modules.

Key Features

• Replaceable IModules: Three IModules give visible LED status so a single failed module can be swapped out instead of replacing the whole unit, saving time and cost.
• Clear Status LEDs: Blue and green LED indicators quickly show whether the unit has power and if surge protection is active, reducing diagnostic guesswork.
• Module Power Switch: The included switch allows safe and convenient disconnection of module power when servicing the unit, making maintenance less disruptive.
• TPMOV Protection: Thermally Protected Metal Oxide Varistor technology reduces hazardous failure modes associated with standard MOVs and provides robust surge suppression.
• Tamper-Proof Design: Type 1 enclosure and tamper-proof IModule doors deliver a durable solution for indoor metal applications and secure installations.
• Connected Equipment Warranty: A $50,000 connected equipment warranty for 10 years provides added peace of mind for covered appliances and electronics.

Who It's For

The IG2240-IMSK is best for homeowners, electricians, and facility managers who want whole-home surge protection that is serviceable over time; the replaceable module design is particularly useful where long-term upkeep is expected. It suits properties with valuable appliances, HVAC systems, computers and entertainment equipment that benefit from continuous protection and a warranty backing.

Customers who need a compact plug-in strip or outlet-level protection should look elsewhere, since this is a panel-mounted whole-home SPD designed for Type 1 and Type 2 style installations. Also, those wanting a bare-bones, non-serviceable SPD might prefer simpler, lower-cost units without modular maintenance features.
