Surge protection
STV 200/400K SERIES
SolaHD STV 200/400K Series oers continuous protection from
damaging voltage transients and electrical noise commonly found
at the service entrance or distribution panel. e modular design of
the STV 200/400K allows for installation exibility and the robust
design allows for installation in the most severe exposure locations.
ey are capable of handling the high-impulse, potentially
damaging transients commonly found at the service entrance or
distribution panels. e modular design of the STV 200/400K
allows for installation exibility. e robust design allows for
placement in the most severe exposure locations.
e STV 200/400K utilizes circuitry to monitor the status of all
protection modes, including neutral to ground. Should protection
be unavailable in any mode, the Green LED will be extinguished,
and the Red LED will be illuminated. In addition, high isolation
form C dry contacts provide remote monitoring of protection
system failure, under voltage, phase and power loss. e STV
200/400K protection integrity monitoring indicates failure for
both shorted or opened protection components.
ese devices are built to meet your unique requirements, and are
available in hardwire, three phase conguration. ey are designed
for years of trouble free operation and require little or no operator
intervention after installation.
Applications
e STV 200/400K Series can be a facility-wide product family
and may be installed from service entrances to distribution panels
to branch panels.
