Transient overvoltage, or power surges, can damage components and drive added costs to repair or replace as well as create unplanned downtime. To prevent these events, the SPD2 series, utilized at power distribution or branch circuits, safeguards components from surges by limiting the fault current to a load or the unit being protected.

“The surge protection device market is growing due to the increasing use of electronic equipment and the need to safeguard it from power fluctuations,” stated Peter Kim, Vice President and General Manager, Littelfuse Industrial Business Unit. “To increase safety and avoid the high costs incurred from equipment downtime, more companies realize the return on investment that SPDs provide and are adopting or designing in these products.”

The SPD2 series is DIN-rail mounted for electrical cabinets and comes in a wide range of operating voltages, including DC power for solar applications. These surge protection devices are suitable for power distribution, electrical loads, industrial controls, computers, and communications as well as HVAC or medical equipment.

The SPD2 series can clamp and withstand high-energy transients to prevent disruption, downtime, and degradation or damage to equipment. Thermal protection eliminates catastrophic failure. Each product part is both UL Recognized and IEC-compliant to reduce inventory and support global usage. A compact footprint increases electrical panel design flexibility. An interlocking tab mechanism withstands vibration. An SPD type and voltage-coded plug prevent the module from being placed in the wrong base, eliminating the risk of improper protection. And finally, a visual life indicator quickly determines module replacement status.

“According to the Electrical Safety Foundation International, equipment being turned on or off causes 60 to 80 percent of industrial power surges within a facility,” offered Richard Dale, Product Manager, Littelfuse Industrial Business Unit. “These disruptive, everyday occurrences can be prevented by using an SPD with higher nominal discharge current—20 kilo amperes (kA)—to avoid unplanned disruptions or stoppages resulting in unfilled orders, missed deadlines, unreliable systems, and/or dangerous situations.”
