Product information made simple

What is the primary application of the Type 2 RELIGRID SPD?

The Type 2 RELIGRID SPD is used to protect:

  • Commercial buildings
  • Industrial panels
  • Residential complexes
  • Data centers
  • Telecom rooms
  • Solar AC & DC distribution boards

from induced lightning surges and internal switching transients, ensuring high system availability and equipment safety.

Type 2 RELIGRID SPDs comply with and are tested according to:

  • IEC 61643-11
  • IS/IEC 61643-11
  • TUV Certification (Independent Third-Party Tested) ✅

TUV certification confirms:

  • Electrical safety
  • Performance reliability
  • Thermal and short-circuit endurance
  • Compliance with international surge protection standards
