The Littelfuse LSP05 thermally protected Surge Protective
Device is a self-protected device which is specially designed
to be used in outdoor and commercial LED lighting fixtures
for transient overvoltage protection. It is constructed with
Littelfuse thermally protected varistor technology. Its built-in
thermal disconnect function provides additional protection
to prevent catastrophic failure and fire hazard even under the
extreme circumstances of varistor end-of-life or sustaining
over voltage conditions. The LSP05 SPD facilitates custom-
er’s product compliance to IEEE C62.41.2 Location Category
C Low and US Dept of Energy MSSLC Model Spec.
