The Cyber Power CSB404 is a compact 4-outlet surge protector providing 450 joules of protection for home and office electronics. It features a 4-foot power cord with a NEMA 5-15P plug and utilizes MOV technology to shield devices from power spikes. The unit includes EMI/RFI noise filtering for cleaner performance and an integrated 15A circuit breaker that enables automatic shutdown to prevent overloads.
The CSB404 utilizes MOV technology to divert up to 22,500A of surge current with a sub-nanosecond response time. It provides 32 dB of EMI/RFI filtration across frequencies up to 100 MHz, ensuring clean power delivery. The unit is housed in an impact-resistant casing and includes keyhole slots for versatile mounting under desks or on walls.
Certified to UL1363 standards, this surge protector features a 15A integrated circuit breaker for reliable overload protection. It is backed by a Limited Lifetime Warranty and a $25,000 Connected Equipment Guarantee, offering professional-grade security for home and office devices. The RoHS-compliant black plastic construction is designed for durability without extra bulk.
This strip is 0.91 lb and measuring 1.97" × 1.38" × 8.44". It features a 4-foot cord with a straight NEMA 5-15P plug, providing flexibility for desktop or floor placement. Built-in keyhole mounting slots allow for a permanent, low-profile installation on various surfaces.
