Surge Protective Devices (SPDs) are designed to reduce the
random energy surges of voltage transients and electrical
noise on the power supply line. Our comprehensive line of
SPDs range from Type 1 Surge Arrestors, the first line of
defense against external surges, to Type 2 Surge Panels
and Type 3 Point-of-Use devices, such as strips and receptacles.
We also offer a variety of Type 4 UL recognized surge protective
components.
All Leviton SPDs incorporate large MOVs as opposed to lower
cost small MOVs in parallel. Large MOVs offer an improved
surge current rating and greater reliability, which ensures
that the product will perform for many years. Finally, Leviton’s
world-class service team will provide on-site application
support on an as-needed basis.
As part of Leviton’s smart grid initiative, Leviton
has identified surge protective devices as a smart grid
component capable of improving the reliability of the North
American power distribution system by providing a level
of protection for electronic circuits that include, e.g.,
smart meters, communication networks, wind turbines and
solar systems. Leviton believes that surge protective devices
may also improve the environment by enabling sensitive electronic
equipment, including computer systems and data center equipment,
to endure for their intended lifecycle. |

| Type
1 Surge Protective Devices are typically mounted on the
line side of the main service entrance. They protect against
external surges caused by lightning or utility capacitor
bank switching.
Leviton Type 1 SPDs offer first line defense against external
surges. They use the largest MOV’s in the business
(40mm & 53mm) and are outdoor rated. Plus, some of our
Type 1 SPDs feature an audible alarm warning that the device
is no longer providing the rated surge protection.

|
| Type
2 Surge Protective Devices typically serve a branch circuit
and protects against residual lightning energy, motor driven
surges and other internally generated surges.
Leviton Type 2 surge panels use UL-recognized surge fuses.
We offer models that contain replaceable modules, surge
counters and 7-Mode protection. We also offer models that
can be used for both Delta and WYE transformers. These SPDs
conform to NEMA LS 1 guidelines. |

Provides point-of-use protection, easily replaceable and
it provides the last line of defense against a lightning
strike.
Leviton offers SPDs to meet all point-of-use applications.
Our surge strips provide triple-redundant protection: Thermal
Cut-off Fuse (TCO), Neutral-Ground Fuse and Circuit Breaker(CB).
We also offer tamper-resistant receptacle versions, IG versions
and quads.
