Phoenix Contact CNUB280DCBB Coaxial Surge Protection Device
The PHOENIX CONTACT CN-UB-280DC-BB is a coaxial surge protection device designed to safeguard sensitive equipment connected to coaxial signal interfaces. Ideal for outdoor applications, this device incorporates a replaceable gas-filled arrester, ensuring long-term reliability. The mounting plate allows for easy and secure installation within control cabinets. It's crucial to use this surge protective device with a transmitter unit that shuts down in the event of a short circuit to meet discharge conditions for DC voltages.
