Littelfuse SPD2 Surge Protection Devices: Deterring Downtimes

8/15/2022

ByLauren Willman

Standard Electric and Littelfuse are offering surge protection devices (SPDs). These devices provide equipment protection from transient overvoltage events.  Any event, no matter how small, can be a problem in the medical device or pharmaceutical industry. The Littelfuse SPDs safeguard expensive components by limiting the fault current to the unit being protected.  While surges can be caused by indirect lightning strikes, 60%-80% are caused by equipment being turned on or off within a facility.

1.     Surge Protection Devices for the 3+0 Configuration:  Available for 120 V to 600 V nominal voltage sub-distribution board applications.

2.     Surge Protection Devices for the 3+1 Configuration:   Available for 240 V to 277 V nominal voltage sub-distribution board applications.

Features & Benefits:

  • Capability to clamp and withstand high-energy transients
  • UL recognized and VDE-IEC compliant in single part number
  • Interlocking tab mechanism
  • No additional overcurrent protection devices required in UL applications
  • Compact footprint
  • Visual life indicator
  • Pluggable modules
  • Thermal protection
  • IP20 protection rating

One Littelfuse Surge Protection Device can be utilized globally, reducing inventory needs and simplifying the allocation of parts.  In addition, limiting the overvoltage headaches, such as costly damage, downtime, and degradation to industrial equipment and controls caused during these events, are mitigated.
