STV 200/400K Series - Surge Protective Devices
SolaHD STV 200/400K Series offers continuous protection
from damaging voltage transients and electrical noise
commonly found at the service entrance or distribution
panel. The modular design of the STV 200/400K allows
for installation flexibility and its robust design allows for
installation in the most severe exposure locations. They are
capable of handling the high-impulse, potentially damaging
transients commonly found at the service entrance or
distribution panels. The modular design of the STV
200/400K allows for installation flexibility. Its robust design
allows for placement in the most severe exposure locations.
The STV 200/400K utilizes patented 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 suppression system failure,
under voltage, phase and power loss. The STV 200/400K
patented suppression integrity monitoring indicates failure
for both shorted or opened suppression components.
These devices are designed to meet UL 1449 (second
edition), UL 1283 and cUL Listed. These units are ANSI/IEEE
C62.11, C62.41, C62.45 Categories A, B, and C3 tested.
They are built to meet your unique requirements, and are
available in hardwire, three phase configuration. They are
designed for years of trouble free operation and require little
or no operator intervention after installation.
