P403U | Home Office Surge Protection
Protect home and office computers, electronics, and home theater equipment

Product Overview


The CyberPower Home Office Surge Protector P403U prevents spikes in energy caused by storms and electrical power surges from reaching your home office equipment such as laptops, small electronics, and chargers. The P403U provides 450 joules of protection, 4 AC outlets, and a 3-ft. power cord with a right-angle plug. It also has 2 USB ports (2.1 Amp) to quickly charge USB-powered devices.

Features of the P403U include automatic shutdown, an EMI/RFI noise filter, metal oxide varistor (MOV) technology, an On/Off switch with integrated 15-Amp circuit breaker, LED indicator (Protected), low profile cord plug, keyhole mounting slots (back), and damage-resistant construction. This surge suppressor comes with a Limited Lifetime Warranty and a $15,000 Connected Equipment Guarantee.

  • Surge Protection
    Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
  • Automatic Shutdown
    Protects connected electronics with the integrated circuit breaker which automatically switches off in the event of an overload that exceeds the model's ability to suppress the signal.
  • EMI/RFI Noise Filter —Maintains clean power for connected equipment by filtering out electromagnetic and radio frequency interference to improve picture and sound quality.
  • Metal Oxide Varistor (MOV) Technology
    Allows normal current to pass through the device, while diverting any surges/spikes through the ground circuit, to safeguard connected electronics and the surge suppressor.
  • On/Off Switch
    Has an integrated 15-amp circuit breaker.
  • Power Cord (3 ft.)
    Connects to power sources, allowing the model to be placed where it’s needed.
  • Low Profile Cord Plug
    Fits tightly behind furniture.
  • LED Indicator
    Illuminates to show surge protection status (Protected).
  • Keyhole Slots
    Enable the model to be placed on a wall or desk.
  • Damage-Resistant Housing
    Ensures maximum durability and prolongs the life of the model.
  • Connected Equipment Guarantee
    CyberPower will repair or replace properly connected equipment if it is damaged by a power surge.
  • Limited Lifetime Warranty
    Covers defects in materials and workmanship in the product under normal use and conditions. See warranty for details.

Why Do I Need A Surge Protector?

Utility power supplied to electrical outlets is sometimes inconsistent. The short-duration voltage surges or spikes that occasionally happen can damage components in electronic devices such as computers and workstations. In addition to equipment damage, irretrievable data loss may occur. In the U.S., the nominal or standard voltage supplied to household and office wiring is 120 volts. A voltage surge or spike can cause electronic components to overheat, either immediately destroying them or causing permanent damage that can lead to premature failure.

A surge protector or surge suppressor provides protection against power surges. This device is located in the power circuit between the utility power outlet and the connected electronic equipment. Surge protectors work by diverting excess voltage to the ground, allowing only the nominal voltage to travel through the wiring to connected devices. This is accomplished using a variable resistance component in the surge protector called a metal oxide varistor (MOV). Under normal voltage conditions, the resistance of the MOV is such that it remains closed. As utility voltage increases beyond nominal, the MOV resistance decreases accordingly which forces the unwanted overvoltage to ground, maintaining a constant flow of nominal voltage to sensitive electronic equipment.

If my surge protector has a ground light, should it be illuminated (green)?

Yes. The ground indicator light should be illuminated. If the light is not illuminated, there is a problem with the AC outlet into which the CyberPower surge suppressor is plugged. If this is the case, please disconnect the surge suppressor until the problem is resolved. The problem must be resolved before the CyberPower surge suppressor can be used.

Common issues with an AC outlet include: bad ground, missed ground, or reversed wiring (usually due to sub-standard wiring, typical in residential housing built prior to 1980). You may need to contact a qualified electrician to repair/upgrade the outlet.

NOTE: Using the CyberPower surge suppressor when the ground indicator light is not illuminated will void the warranty.
