The enhanced K21 surge protection cables intended for indoor use prevent hardware damages caused by current surges and voltage spikes.
A single-phase AC protector defends against lightning overvoltage for both common and differential modes.
The surge protection unit is built into a standard power cable intended for RAD devices that do not have integrated protection.
To match a specific K21 cable to your device, please contact your RAD representative. For example:
• ETX-203AX, ETX-2i-64E1, ETS-1 can use CBL-K21-EURO
• ETX-2i-100G can use CBL-K21-EURO/EN
• ETX-2i does not require any K21 cable.
