Rackmount Surge Protection

The CyberPower RKBS15S2F8R is a 1U rackmount surge suppressor built for server rooms and network closets. It provides ten NEMA 5-15R outlets split between two front and eight rear positions. A 15-foot power cord connects the unit to a 120V AC supply rated for 15 amps. Rugged metal housing shields internal components in demanding environments.

3600 Joule Suppression Limits

The suppressor absorbs up to 3600 joules of surge energy with a clamping voltage of 400V across normal, hot and ground lines. Maximum surge current reaches 180,000 amps and maximum surge voltage hits 6,000 volts. Response time is one nanosecond while EMI/RFI filtration attenuates noise up to 50 dB. UL1363 and UL1449 certifications by ETL and CSA C22.2 confirm compliance.

Ten Outlets and 15-Amp Capacity

Ten outlets accommodate multiple servers, switches and peripherals on a single 15-amp circuit breaker. The 15-foot cord offers placement flexibility within standard rack rows. Unit dimensions of 1.75 by 17.5 by 2.25 inches fit a 1U space weighing 4.01 lbs. Builds requiring 20-amp service or higher joule ratings need a different model.

Questions about this item

Should I pick the 15-amp model or the 20-amp version for my rack?

This unit is the 15-amp model rated at 15 A output capacity. If your equipment draws more than 15 A total, you would need the 20-amp Rackbar variant instead.

What does the 3600-joule rating actually protect in a live rack?

The 3600 J rating means the suppressor can absorb that much surge energy across normal-hot, normal-ground and hot-ground modes before the protective components degrade, with a 400 V clamping voltage.

Does the NEMA 5-15R outlet standard limit what I can plug in?

Yes, the ten NEMA 5-15R receptacles accept only standard 120 V North American plugs and the total load must stay within the 15 A circuit-breaker limit.
