APC’s new SurgeArrest was designed in response to customer requests for additional safety and convenience features. APC introduced plug-activated safety shutter and cord management to deliver increased security and ease of use, while superior power line and data line surge protection prevents damaging surge and spikes from ever reaching your equipment. Lightning and Surge Protection To prevent damage to your equipment from power surges and spikes. IEEE let-through ratings and regulatory agency compliance APC's surge protectors undergo stringent testing by IEEE, and are awarded "let-through ratings", which indicate the maximum voltage level that can possibly reach your equipment after a surge or voltage spike has passed through a surge protector. Lower IEEE let-through ratings indicate better protection and performance. APC’s Essential SurgeArrest series offers optimal performance with a let-through rating of less than 330V for North American products, and a rating of less than 15% for products sold worldwide. All APC products comply with local agency safety requirements, including UL in North America and CE/Kema/Gost/C-tick/A-Tick/Telepermit in their respective regions. Data-line Protection Protection of data lines (Ethernet, Coaxial and Phone lines) ensures complete protection of your equipment from surges. It is very important to protect your equipment from “back door” surges traveling through data lines, as they can be as damaging to your equipment as surges traveling over power lines. Noise Filtering Surge Protector attenuates EMI/RFI line noise that can cause data errors and keyboard lockups, ensuring better performance of protected equipment. Catastrophic Event Protection SurgeArrest's components such as MOVs and Thermal fuse ensure instantaneous reaction to lightning strikes and wiring faults. If the surge components are damaged due to power spike or over voltage, excess power cannot reach your equipment. Unlike APC's SurgeArrest products, most surge suppressors continue to let power through even after circuits have been damaged, leaving your equipment exposed to other damaging surges. Fail Safe Mode Most other surge suppressors continue to let power through even after their circuits have been damaged, leaving your equipment exposed to future surges. APC’s SurgeArrest fail safe, which means that once the circuit of an APC SurgeArrest has been compromised the unit disconnects equipment from the power supply ensuring that no damaging surges reach your equipment. Overload Indicator Indicator illuminates when connected equipment draws more power than unit’s capacity. To remedy the condition, unplug less vital equipment. Receptacle Shock Safety Shutters Shutters protect users from accidental contact with unused outlets. Phone Line Splitter Allows use of two pieces of equipment at once, such as a modem and phone. 180 degree Rotating Cord Retainer Offers flexibility in positioning the SurgeArrest, and in routing the power cord. Transformer Block Spacing Connect bulky transformer block plugs without covering up other outlets. Adjustable Cable Management Keeps cords and cables neat and organized. Building wiring fault indicator If this indicator goes out, surge suppression circuitry has been damaged by a heavy strike or power line surge. Protection Working Indicator If this indicator goes out, surge suppression circuitry has been damaged by a heavy strike or power line surge.
