About Siemens QSA2020SPD Whole House Surge Protection
Description Amazon.com In today's electronic world, your home's electrical, phone and cable systems are incomplete unless they incorporate surge protection. Since most everything in the home is microelectronic based, it is not practical to solely rely on surge protected plug strips. By installing this Siemens circuit breaker and surge protective device (SPD) in the load center of your home, surge protection is provided for all branch circuits. This version (model QSA2020SPD) is rated at 20 amps, and it's also available in a 15 amp version. The 20 amp QSA2020SPD surge protection device (view larger). The QSA2020SPD features a highly effective TVSS integrated with two 1-pole circuit breakers and incorporates the robust features of a secondary circuit breaker surge arrester with a lower clamping voltage ratings. 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. Two green LEDs provide protection status notification, and the device will notify you of any loss of surge protection by tripping one or both of the circuit breakers. These breakers should be used for circuit protection of frequently used household or facility circuits as the lights and devices connected to these circuits provide an effective indication that surge protection is being provided. All Type QP circuit breakers and SPD are plug-on style, with load terminals provided. The devices are rated for 120/240V AC and are calibrated for 40 degrees C maximum ambient applications. 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.
