Lighting Surge Protector (LSP) modules are specially designed to be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection. They are constructed with Littelfuse thermally protected varistor technology which prevents catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or sustaining over voltage conditions. The LSP modules facilitate customer’s product compliance to IEEE C62.41.2 Location Category C Low and US Department of Energy MSSLC Model Spec.

There are two series: the LSP05 (5K Amp Nominal Surge rating, 10 KA Max) and LSP10 (10K Amp nominal surge rating, 20K Amp Max). Each series has multiple voltage ranges ranging from 120V to 480V. The LSP Thermally Protected Varistor Module is replaceable and reduces maintenance costs while extending luminaire lifetime. The indication wire can be connected to an indication circuit for luminaire monitoring purposes.
