BLITZDUCTOR XT Ex (i) – Protection Modules

Surge arrester for intrinsically safe measuring circuits and bus systems
  • Maximum discharge capacity for two-pole, three-pole or four-pole interfaces
  • Low voltage protection level, capable of protecting terminal equipment
  • Wide range of approvals: ATEX, IECEx, CSA Hazloc
Arrester consists of a protection module and a base part
  • Easy replacement of protection modules without force
  • All protection components are integrated in the protection module
  • Arrester with integrated RFID LifeCheck for preventive arrester monitoring
Functional and attractive design
  • DIN rail mounted arrester with integrated earthing
  • Minimum space requirements, two pairs over a width of 12 mm
  • Vibration and shock-tested for safe operation

Details

Prewired surge arrester unit ITAK EXI BXT 24.
lorem ipsum
Two-part design comprising a universal base part and an application-specific protection module.
lorem ipsum
The module locking mechanism ensures that the module is vibration-proof and protected against polarity reversal.
