Product Description
Due to the evolution
of electronics and
microprocessors in the
home, there is a continuous
challenge to provide quality
(clean) power for electronic
loads such as appliances,
computers/home office and
entertainment systems.
Surges caused by lightning,
utility grid switching and
other sources travel on
current carrying conductors
throughout the home, which
can affect and destroy
sensitive electronic loads.
Eaton offers a comprehensive
family of surge products for
use at service entrances.
These products can help
protect sensitive electronics
against the damaging effects
of surges.
Application Description

Two stages of surge
suppression are
recommended to provide
the best protection for
electronic equipment.
Two-stage surge suppression
should be provided for all
cables entering a home,
including power, Internet,
coaxial and telephone.

surge protection units
provide premier surge
protection for AC power
