The SPD2-300-4P0-R from Littelfuse is a Surge Protector Module that has been designed to provide equipment protection from transient overvoltage events lasting in the order of micro-seconds by limiting the voltage to the equipment during these events. It requires an input voltage of up to 300 V. This VDE-IEC-compliant surge protector offers the capability to clamp and withstand high-energy transients, thereby ensuring low residual voltage during high-energy surge events and higher nominal discharge current. It consists of a visual life indicator, an interlocking tab mechanism to withstand vibrations, pluggable RC connectors, and is touch-safe.

This IP20-rated surge protector offers built-in over-voltage protection (OVP), over-current protection (OCP), and thermal protection to prevent over-heating or over-load-related damages. It is available in a DIN-rail mount package and is ideal for power distribution, industrial controls, electrical loads, computers and communications, and HVAC or medical equipment applications.
