LSP10 Module Series
Description
The Littelfuse LSP10 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. LSP10 series connected option
allows clear indication of thermal fault protection by discon-
necting power to luminaire thereby signally SPD module
replacement. The LSP10 SPD facilitates customer’s product
compliance to IEEE C62.41.2 Location Category C High and
US Dept of Energy MSSLC Model Spec.
