TTC-6-3-HF-F-M-EX-12DC-UT-I - Surge protection device

Surge protection with integrated status indicator and knife disconnection for a 3-wire Ex i signal circuit with common reference potential. For HF applications. Indirect grounding via gas-filled surge arrester, HART-compatible.

  • Space-saving and cost-saving with a narrow overall width of just 6 mm
  • Continuous monitoring of protective devices, plus mechanical status indicator with optional remote signaling
  • Finding the right product for all possible requirements in MCR applications is easy, thanks to the complete range of products with customized features
  • Signal circuits easily interrupted for maintenance work, thanks to vertical knife disconnection
