Product/Part Numbers Benefits 特性

Type 2 Surge Protection Devices

SPD2
Positioned at the power distribution or branch circuit location, it safeguards components from power fluctuations or surges by limiting the fault current to a load or the unit being protected to prevent equipment damage or downtime.
  • Capability to clamp and withstand high-energy transients to prevent disruption, downtime, and degradation or damage to equipment
  • Thermal protection to eliminate catastrophic failure
  • UL Recognized and IEC Compliant in one part number to reduce inventory and support global usage
  • DIN-rail mounted and compact footprint to increase panel design flexibility
  • An SPD type and voltage-coded plug to prevent module from being placed in wrong base, eliminating the risk of improper protection
