Siemens QSA2020SPD Whole House Surge Protection with Two 20-Amp Circuit Breakers for Use Only on Siemens Panels

Product Description
Siemens SPD device provides whole house surge protection. This device takes up the space of two standard single pole breakers, but also includes two single pole breakers so you do not lose any space in your Load Center. Once connected in the panel, the SPD device protects the entire panel and all branch circuits from surges, not just the two circuits connected to the SPD. Initial clamping level is 240 Volts. LED's provide protection status notification. Siemens strongly recommends against the use of "used" breakers.


Surge Protective Devices
To effectively surge protect your appliances and other sensitive electronic equipment, you need to stop surges before they get into your home and also control surges generated inside your home. Damaging surges enter your home primarily through the main utility power source, coax and telephone services. When left unprotected, surges will permeate throughout the home damaging electronics and appliances.

What is a surge?
A surge, sometimes called a transient or a spike, is a brief burst of energy (voltage and current). The most damaging surges enter through your home's power, cable and telephone lines. However, the majority of surges originate within the home from the action of motor based appliances like dishwashers, refrigerators, garage door openers, etc.

How do surges affect my equipment?
Large surges can damage equipment by "burning up" the internal components of your sensitive electronic equipment and appliances. Moderate surges disrupt equipment operation and damage internal components. Lower energy surges degrade equipment, which is referred to in the industry as "electronic rust. "

Why do you need this type of surge protection?
The only way to surge protect microelectronic based appliances is through the application of an incoming service entrance surge protector like a Siemens SPD.
