K9001: 10 Way Analogue Voice (Line) Protector
K9001: 10 Way Analogue Voice (Line) Protector The Branell K9001 is an advanced analogue protection magazine compatible for use with LSA plus modules. The product protects up to ten subscriber lines against lightning and power-induced overvoltages and has a fail-safe system to protect connected equipment when the magazine reaches the end of its service life. The K9001 was designed to be both cost-effective and to offer superior surge clamping performance. State of the art hybrid protection components combined with a patented earthing system achieve this aim. The unit also incorporates high quality gold-plated contacts to ensure low contact resistance, label holder for easy line identification and is housed in a flame-retardant enclosure.
