Littelfuse SPD2 Series Surge Protection Devices provide protection against transient overvoltage events by clamping excess voltage and safeguarding equipment. These devices minimize equipment damage and reduce downtime during microsecond-level surge events. The modules integrate thermal protection to eliminate catastrophic failures and feature a compact footprint for flexible panel designs. These components handle high-energy transients and comply with UL and VDE-IEC standards for global use. These surge protection devices are suited for industrial control panels, commercial buildings, and renewable energy systems.

When you hear surge, you think of lightning surges: transient overvoltage events caused by a lightning strike. But as many as 80% of surges are caused by facility equipment being turned on or off. Littelfuse’s SPD2 series of Type 2 surge protection devices has a maximum discharge current rating of up to 50kA for those larger, single-occurring surges and a nominal discharge current rating of up to 20kA for those more routine surges.
They come in a variety of voltage ratings, including options for photovoltaic systems and are thermally protected to eliminate catastrophic failure. The devices have a compact footprint for panel design flexibility. They feature a pluggable module for easy replacement and a visual life indicator to avoid loss of protection. The modules are coded by type and voltage rating to prevent plugging the wrong module into the base. The SPD2 series is UL recognized and VDE-IEC compliant, allowing a single part number to be used globally.
