Overview Premium protection for home, corporate, retail, telecom and industrial applications, the EURO-4 Isobar 4-Outlet 230V Surge Protector features a surge protection rating of 680 joules to defend your sensitive electronics against surges and spikes. The EURO-R features four widely spaced C13 outlets, which are arranged in two exclusive isolated filter banks that prevent equipment connected to one bank from interacting with equipment connected to the other. These internal barriers also prevent disruptive line noise from causing A/V distortion, computer lock-ups, data errors and similar problems. Large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors remove EMI/RFI interference and prevent system crashes, reboots and performance problems. Because residential power outlets have three wireshot line (H), neutral (N) and ground (G)the EURO-4 protects all three, covering two protection modes: full normal mode (H-N) and common mode (N-G/H-G). An integrated 9A circuit breaker protects all outlets and shuts down connected equipment in the event of an overload. A lighted on/off switch provides one-touch control over connected components. A C14 inlet accepts a variety of detachable power cords, such as the included six-foot (1.8 meters) C13 cable. An all-metal housing ensures long life and durability.
