SPDN Surge Protective Devices

Littelfuse SPDN Surge Protective Devices (SPDs) protect equipment from high-energy transient overvoltage events. The SPDs offer more direct modes of protection within a small package, including L-N, L-G, and N-G. The Littelfuse SPDN SPDs feature a stacked, thermally protected Metal Oxide Varistor (MOV) design, clamping capability, and an external LED indicator. The SPDN series operates with a 50kA to 130kA max surge current rating range and within a 50Hz to 60Hz frequency range. The SPDs are RoHS/REACH compliant and ideal for construction, food/beverage, HVAC/refrigeration (HVAC/R), light industrial, water/wastewater, and oil and gas applications.
