Six-outlet surge protection

The CyberPower CSB604 provides six NEMA 5-15R outlets with 900 joules of surge protection and a four-foot cord. It uses MOV technology to guard connected electronics against line abnormalities and lightning surges. EMI/RFI filters block unwanted line noise between 150 KHz and 100 MHz. A 15-amp circuit breaker adds overcurrent protection.

Home and office electronics

This unit suits desktop computers, printers, phones, modems and consumer electronics needing basic surge suppression. Buyers who need more than six protected outlets should look at a different model. It is not designed for hard-wired installations or industrial three-phase power. The cord length limits placement to within four feet of a wall socket.

900-joule energy rating

The 900-joule rating is the single figure that determines how much surge energy the device can absorb before protection degrades. Clamping voltage is 400 volts across line-neutral, line-ground and neutral-ground modes. Maximum surge current is rated at 45,000 amps total. Response time is under one nanosecond.

Questions about this item

What comes in the box with the CSB604 surge protector?

The package includes the surge protector unit with six NEMA 5-15R outlets, a 4-foot power cord, and an integrated 15A circuit breaker.

How do I know if 900 joules is enough for my computer and monitor?

A 900-joule rating suits typical desktop setups with a PC, monitor, and peripherals; higher-value home-theatre gear may warrant a model with a larger joule figure.

What does the 400V clamping voltage mean for my equipment?

It means the suppressor diverts excess voltage once it exceeds 400 volts, limiting the spike that reaches connected devices.
