UL1449: Standard rated by Underwriters Laboratories as minimum protection standards for surge protectors. It rates suppressors by amount of voltage passage they allow.
Protection Indicator: LED indicator as to metal-oxide varistors functioning. MOVs do not last forever – one lightening strike can fry them out.
Line Conditioning: Most surge protectors contain this feature. It filters out line noise using a toroidal choke coil to “condition” current.
Power Switch: There are manual on/off power switches as well as circuit switches. Circuit switches are useful for keeping some components running while others are shut off.
Circuit Breaker or Fuse: A fuse is a resistor that can conduct current below a certain level. If current is higher than acceptable, heat burns fuse and cuts off circuit. Breakers are more economical than fuses as they do not have to be replaced.
Protection Guarantee: Read terms and conditions carefully! It is important to understand your consumer rights in event of damage to devices your surge protector neglects to protect (Kozierok). According to data published on Hewlett Packard’s website, recent statistics reveal 63 percent of all electronics casualties are result of a power related problem. Most affected are devices using computer chips and high-speed microprocessors. Unprotected computers can suffer hardware degradation and extensive damage when exposed to power surges (Power Protect Your Computer).
The cost of a surge protector varies greatly depending on user needs. Basic models sell for as low as $10 but one should be cautious as to capabilities these units offer.
NOTE: It is important to connect all peripheral equipment to surge protector for complete protection. This includes phone jacks, modems, cables, and any other external devices that will receive electrical current.
