Littelfuse Introduces New SPD2 Type 2 Surge Protection Device (SPD) Product Line

Industrial Power Fluctuation Protection for Sensitive Equipment at

CHICAGO–(BUSINESS WIRE)–Littelfuse, Inc. (NASDAQ: LFUS), a global manufacturer of leading
technologies in circuit protection, power control and sensing, today
announced the launch of its SPD2 series of Type 2 surge protection
devices. 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
, 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. The product is ideal for power distribution, electrical
loads, industrial controls, computers and communications as well as HVAC
or medical equipment. The SPD2 features include:

  • Capability to clamp and withstand high-energy transients to prevent
    disruption, downtime, and degradation or damage to equipment
  • Thermal protection to eliminate catastrophic failure
  • Each part is both UL Recognized and IEC-compliant to reduce inventory
    and support global usage
  • A compact footprint to increase electrical panel design flexibility
  • An interlocking tab mechanism to withstand vibration
  • An SPD type and voltage-coded plug to prevent the module from being
    placed in the wrong base, eliminating the risk of improper protection
  • A visual life indicator for quick determination of module replacement

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.”
