Rackmount Surge Protection for Demanding

The CyberPower RKBS20S2F10R is a 1U rackmount surge suppressor built for data centres and electrically demanding environments. It provides 12 NEMA 5-20R outlets split between two front and ten rear positions. A 15-foot cord with a NEMA 5-20P plug feeds 120V 20A power to connected equipment. The rugged metal housing supports horizontal or vertical mounting.

Sustained Surge Handling and Filtering

The unit carries a 1,800-joule suppression rating and a maximum surge current of 90,000 amps at 6,000 volts. Clamping voltages are 400V for normal-hot and hot-ground, and 500V for normal-ground. Response time is 1 nanosecond. EMI/RFI filtration attenuates noise by up to 50 dB, protecting sensitive gear during prolonged electrical disturbances.

Industrial Build with Visual Status

A power-on LED confirms the unit is active and the protection circuit is functional. The 1.75 by 17.5 by 2.25 inch metal chassis weighs 4.75 lbs and includes a cord retention tray for secure cable management. Certifications include UL 1363, UL 1449 via ETL and CSA C22.2. The package is covered by a lifetime warranty and a $150,000 connected equipment guarantee.

Questions about this item

Does the 1,800 J surge protector generate heat or noise when powering a full 20 A load all day?

The unit has no fan or active cooling, so it runs silently and produces only minimal warmth from the internal suppression components during continuous 20 A operation.

What plug and circuit must already be in place for the NEMA 5-20P input to work?

A 120 V, 20 A branch circuit with a NEMA 5-20R receptacle is required; a standard 15 A outlet will not accept the 5-20P plug.

Will the 400 V clamping voltage protect older 120 V gear that lacks its own MOVs?

Yes, the 400 V line-to-neutral clamp limits transients well below the withstand threshold of legacy 120 V equipment connected to the 12 NEMA 5-20R outlets.
