Surge Suppressors or Power Strips (4083)

Government / agencyIndexed Oct 28, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20160122-CF907-2147424442. Severity: Unspecified. Matched catalog product: Supco Supco SCM150. Source model text: SCM 150. Incident: I believe this commonly installed surge protector is inherently unsafe. It is commonly used to protect HVAC equipment in a power surge situation, however it appears to be prone to starting fires as it does this. Other devices on the market do not have the same design flaw. Our surge protector was tripped earlier this month and resulted in a fire to the exterior of our home. Fortunately our house is brick and so the damage was contained to some charring on the exterior of the house.

Surge Suppressors or Power Strips (4083)

Government / agencyIndexed Oct 22, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20141119-CBB75-2147438731. Matched catalog product: Supco Supco SCM150. Source model text: Supco SCM150,Type 2 SPD,120/140V,60Hz,Single Phase Surge Pr. Incident: In October of 2012, a customer called to inform one of our HVAC service centers that a fire originating in the outside disconnect box of his air conditioning compressor had burned the side of his home. The fire department responded and identified the source as the "Supco SCM150, Type 2 SPD,120/140V, 60Hz, Single Phase Surge Protector." We reported the claim to our parent company, which took over the investigation and management of the insurance claim. Though we could find no recall on the CPSC site, the center stopped using the Supco surge protectors as a precaution. A little over a year later, we became an independent company after our parent company sold us and we never learned the outcome of their investigation.

Government / agencyIndexed Oct 16, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20190306-E8BB2-2147382338. Severity: Incident, No Injury. Product: Supco Supco SCM150 (Supco Power Surge Protector connected to my AC unit. Approximately 3x3.5inch black box with Supco SCM150 Type 2 SPD written on it.). Incident: On Tuesday February 26, 2019 at 9am I was sitting in my backyard when I heard a loud pop and spark like noises.I turned to look in the direction of that noise and saw flames coming from the side of my house where my AC unit was located. I grabbed my hose and put out the fire only to learn that the fire was started by the Supco 150 power surge protector. While I waited for my AC company to come check this out the fire started up again. At this point I called 911. Needless to say if I had not been home or if this happened in the middle of the night this could have ended in tragedy. My AC technician told me and I quote �I have installed thousands of these devices and yours is the third fire I have seen.� It scares me to think how long before the thousands he has installed catch on fire. I came to learn that UL had issued a warning on this product in a public notice on July 29, 2016. It saddens me to think that this product is still in use and can still be purchased on E-Bay. If you Google- supco surge protector fire- you will see more accounts of this product catching fire. There should be an immediate recall on this product.
