Description

SPD-10S-277S 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 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. It also features a built-in LED
indicator that notifies when replacement of the module is needed.
