Introduction to Surge Protection Devices

Surge Protection Devices Overview

Surges may be caused by an indirect lightning strike but, the majority are caused by equipment being turned on or off within a facility. These surges damage components costing money to repair or replace as well as create unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations. The Littelfuse Surge Protection Device (Type 2) SPD2 Series for branch circuits safeguards components from transient overvoltage or surges by limiting the fault current to a load or the unit being protected.

The DIN-rail mounted, pluggable module device offers a compact footprint for panel design flexibility as well as a quick and easy installation. With UL and VDE-IEC compliance in one component, the SPD2 Series reduces inventory needs and simplifies allocation of parts.

The SPD2 Series is ideal for power distribution (load centers, transformers, generators), electrical loads (motors, fans, heaters, blowers, ballasts), industrial controls (programable logic controllers, motor controls, variable-frequency drives, proximity sensors, barcoding equipment, machine vision systems), computers and communications (LANs, WANs, intercoms, and fire, security, UPS or building management systems), and HVAC or medical equipment.
