What is the difference between all of the units? Which one do I need?...While most people choose the LA-302R and the CA-302 units for total home protection, if you are unsure, start with our Product Wizard Selector! In addition, here is a brief explanation of each product and what it can do for you:

Lightning Arrestors
A lightning arrestor helps to provide immediate, and reliable protection against the high voltage surge (such as that of a lightning strike) on your building or power lines. These units will last a lifetime, except in the extreme cases of rare excess surges. This particular type of surge is particularly devastating to electrical components, almost always rendering them useless. In addition, if you are not protected against high voltage surges, an electrical fire can easily be started within moments as a result of high current levels rushing through building wires. Your breaker box is incapable of providing protection against this "lightning fast" surge of electricity. By the time your breaker has switched off, the surge has literally already done its damage. Although a lightning arrestor helps to prevent high voltage spikes from infiltrating your circuits, it does not protect against the common smaller surges.

Surge Capacitors
Surge Capacitors pick up where lightning arrestors leave off and protect you against the smaller surges, which occur every day. Varying levels of current occurring when appliances turn on and off, or when power to a local grid is lost or regained brings on these surges. Over time, the constant wear-and-tear of these surges will permanently damage delicate electrical components. While surge capacitors are fully capable of guarding against the smaller fluctuations in current and voltage, they are unable to provide protection against large voltage spikes. This is why it is best to have both a lightning arrestor and a surge capacitor installed in your home.

Data Line Circuit Protectors
The final line of defense in the Delta Surge Protectors arsenal is the Data Line Circuit Protector. Put simply, this unit guards against electrical surges in telephone and data lines, which are often left connected to computers and televisions during thunderstorms. It is a documented fact that literally hundreds of people talking on "land-line" telephones are killed every year during electrical storms by current coming straight through the telephone handset. With a Data Line Circuit Protector, you are afforded some protection against these often overlooked and potentially lethal surges.
