Surge Arresters – Type 3

SFL Protector
• Surge protection with monitoring device and disconnector
• Interference suppressor filter
• Enhanced safety due to fault-proof Y protective circuit
• Mains switch with operating state indication (SFL PRO 6X only)
• 2 m connection cable for flexible use in a wide range
of applications
• Visual operating state (green) and fault indicator (red)

Multiple socket outlet for protecting the power supply circuits of electronic equip-
ment against transients and high-frequency interference voltages. For installation
in conformity with the lightning protection zone concept at the boundaries from
1 – 2 and higher.

SFL PRO 6X: Surge protective multiple socket outlet with interference suppressor filter
SFL PRO 6X 19": Surge protective multiple socket outlet with mains filter for 482.6 mm (19 inch) data cabinets

The SFL Protector surge arrester complements the wide range of Red/Line
surge protective devices. The combination of surge protection and mains
filter makes the six-way socket outlet a powerful device for protecting
electronic consumers in final circuits. The harmonised surge protection and
filter functions complement one another and prevent core saturation of
the filter in case of high-level transients. The integrated mains filter is
optimised for protection against balanced and unbalanced high-frequen-
cy interferences. The nominal current carrying capability of 16 A allows
flexible use of these devices in final circuits.
The fault-proof Y protection circuit ensures protection even if the phase
and neutral conductor in standard earthed socket outlets cannot be iden-
tified. The standard green and red LEDs indicate the operating state of the
surge protective device.
The SFL PRO 6X 19" has been specifically developed for use in network
cabinets and therefore provides optimal protection for terminal equip-
ment in this critical field of application.
