Excelente protector de alzas de voltaje

As advertised

Unit was shipped in Mfgr. box, not an amazon bag. The 4 screws were missing/probably fell out. And unfortunately the leads were too short and my inspector did not want me to splice them so had to return the unit.

I am not a certified electrician. The following information is for review purposes and suggestions only. Contact your local professional for exact information regarding your city or county requirements. Study the installation manual before attempting to work on high voltage equipment. Turn off all power to breaker box and check electrical status with voltage sensing equipment before installation.This Surge protector was easy to install. However, this fact is a little hard to find in their manual. You will need to install a 2 pole 15amp breaker to hook it to. This is type of breaker is generally regarded as a 240 volt breaker as it will have two switches on it. This is important because the surge protector must protect both sides of the main breaker box, only a 240 volt breaker will do that. There are four wires coming off this surge protector. Connect green one to the ground bar, white one to the common bar and the other two are connected separately, one to each side of the 240 volt breaker. Also, it is important that the 240 volt breaker be installed as the first breaker in the box, in other words, closest to the large wires coming into the box. Why? Because you want the electrical surge to come through the main wires and hit the surge protector first. You may need to move a beaker or two in the box to make this happen. Before purchasing, make sure there is enough room in the breaker box to accommodate another 240volt breaker.If this unit is installed in a secondary/sub panel, a ground wire from the panel should be attached from the ground bar to a copper stake that has been driven into the ground. This is proper procedure for all sub panels.There are some good videos of this product being installed on YouTube. While you’re there, check out proper sub panel ground wiring.I hope this helps you.

Have a Licensed Electrician install this. My son is one, and had this whole house surge protector in about an hour. I am glad we finally did this, since Tornado season is coming, and this house has a ton of electronics.

Opened this device to see what it was comprised of, and am pleasantly surprised with the build quality. It appears to be a scaled down version of the Eaton Ultimate Whole House Surge Protector. https://smile.amazon.com/gp/product/B01AQAKRSS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1The circuit board appears to be a depopulated version of the Ultimate's.The primary mechanism to protect your home from power surges are 2 metal oxide varistors (MOVs) per leg, 4 MOVs in total.The MOVs are Sincera T25D241K. The best info I can find, state that they are rated for 150V, meaning that any voltages over 150V are shunted to ground/neutral, protecting everything on both legs of your panel. Their maximum clamping voltage is 400V. (I am not an electrical design engineer, but this is my understanding of these values having done some amateur electronics projects)As I understand surge suppression, while this will not protect from direct lightening strikes, it will protect you from spikes as appliances turn on/off and some amount of transient voltages that are induced into wiring from NEARBY lightning strikes. There is not much any homeowner can do to protect from a direct lightning other than having lightning rods with great grounding.The housing is very sturdy plastic and is outdoor rated. The circuit board is silicone dipped to protect it from moisture and the housing has rubber gaskets on the screws holding the halves together. If installing outside I would install it under a circuit box to provide some protection from direct rain.

I live in an area where blackouts are the rule of the day. For many years before I installed my Eaton CHSPT2SURGE SPD I had replaced, TVs, SPLIT Units and refrigerators electronic control units due to electrical spikes after blackouts. It performs as advertised protecting my electronics til this day.The installation was simple as the length of the cords allow me to install at a convenient location. Size and appearance is perfect as the LED will provide the SPD status.
