for medium and low exposure level applications
that require cost-effective, high-quality system
protection including:
•
Residential/small business
•
Light industrial
•
Light commercial
•
Service entrance and branch panel protection

CVX surge protective device
General description
CVX050/100
With more than 20 years of experience in the surge suppression
industry and extensive R&D initiatives, Eaton is considered a
world leader in SPD manufacturing. All of Eaton’s products are
manufactured in an ISOT 9001:2000 and ISO 14001 certified facility.
Eaton CVX050/100 models are rugged, cost-effective, high-quality
SPDs that feature self-protected metal oxide varistors (MOVs) that
eliminate the failure characteristics of standard metal oxide varistors.
The self-protected MOV is a fail-safe device that monitors the status
of the metal oxide disk and disconnects itself from the power
system when the disk is approaching breakdown.
The CVX050/100 is easy to install adjacent or even internal to
electrical equipment. When installing an SPD in a retrofit environment,
it is important to mount the device as close to the electrical equipment
as possible. Keep the wiring (lead length) between the electrical
equipment and the SPD as short as possible, and twist or wire tie
the conductors together to reduce the wire’s impedance factor.
