DitekDTK-120/240CM+ Surge ARRESTOR, Parallel Protector, Multi-Purpose, NEMA 4X, UL1449 Listed, SPD, Type 1, 2W(+G), 120/240VAC

Easy to install. Installs in about 10 minutes.

Perfect! The DIY installation was straight forward and basically very easy. No issues at all. I did pigtail the wires so there was only one wire attached to each of the two connecting lugs. I also like the fact that there is a visable clue that the unit is functining properly via the green LED light. The AC company I use for maintenace cleaning made a very compelling discussion for having an HVAC surge protector installed. But unfortunately they were quoting over $300 to install one. The ease of the installation and the cost of this actual product made this purchase a perfect alternative to the AC company.

Five stars for ease of installation, however I can't yet attest to the effectiveness of the product; I'll assume it's functional for now and will update the review if that changes. I installed one on each of my two AC unit disconnects, and purchased a third as a spare in the event this sacrificial device does its job (in which event it will need to be removed/replaced).

safe and neat

Stuff like this is hard to review due to the nature of how it works. If it's doing its job, then you will never have a problem, thus wondering if you ever needed it in the first place. All I can say is that it has great specs, is easy to install, and is cheap insurance if you live anywhere there are surges in the power grid. I live in the south where the lightning will kill all that you love and hold dear (air conditioner) so these are cheap insurance to prevent the worst.

Todo se ve según la descripción. Fácil instalación. Ahora a esperar que cumpla con su función. Mejoraría el empaque porque es muy débil. El artículo merece un empaque más robusto, mejor protección. Por eso califico con 4 estrellas

Usa made, quality, reasonable price,

This new purchase is Replaceing an older model that did its job saving a electrical panel. Worth every penny.
