SP Series  Class II / Type 2 DIN-rail Surge Protection Device (SPD) – IEC Standard

Prosurge SP series DIN-rail surge protection device (SPD) is Class II / Type 2 (IEC 61643-11) pluggable surge protector, designed for low-voltage power supply system protection against the damage from surges and spikes caused by lightning and other electrical sources.

SP series surge protection device features Prosurge’s global patented fail-safe and self-protected technology, offering quick thermal response and perfect cut-off function and providing fast and reliable protection for various power supply systems.

Built with window fault indication and optional remote alarm contact, it can monitor the operating status of the SPD itself.

SP Series  Class II / Type 2 DIN-rail Surge Protection Device (SPD) Features

  • KEMA certified T2 SPD with high energy MOV technology
  • High reliability due to global patented thermally protected with special arc-extinguish device (TPAE technology).
  • High surge current discharge capacity up to 40kA 8/20
  • Pluggable module for easy replacement
  • Degradation indication & optional remote signal contact.
  • Comply with IEC/EN 61643-11, UL 1449 4th, IEEE C62.41, CSA C22.2
