TTC-6-1X2-F-M-24DC-PT-I - Surge protection device
Surge protection with integrated status indicator and knife disconnection for a 2-wire floating signal circuit, e.g., 0(4) mA ... 20 mA current loop. Indirect grounding via gas discharge tube, HART-compatible. Can be used in safety-related circuits up to SIL 3.
- 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
