Surge protection with integrated status indicator and knife disconnection for three signal wires with common
reference potential. For HF applications and telecommunications interfaces without supply voltage (up to 90
Mbps). Indirect grounding via gas-filled surge arrester.
Why buy this product
Space-saving installation due to the narrow overall width of 6.2 mm
Signaling without additional auxiliary power, thanks to the mechanical status indicator
Optional remote signaling module monitors up to 40 items, without additional wiring
Quick and tool-free installation of surge protective devices, thanks to Push-in connection technology
Signal circuits easily interrupted for maintenance work, thanks to vertical knife disconnection
Safe behavior in the event of overload, thanks to the integrated disconnect device
Grounded or insulated shield grounding, thanks to the third terminal point on the surge protective device
