Surge Arrester, Type II, 275 V AC, 20 kA, Replaceable Insert, 1+N Pole

The 103349 surge arrester from Noark is a Class 2 device designed to protect electrical systems from overvoltages typically associated with transient fast switching operations or indirect lightning strikes. It features a voltage protection level of 275 V AC and a maximum discharge current capacity of 20 kA, making it suitable for installation in both main boards and sub-distribution boards. For optimal protection, it is recommended to install these surge arresters at intervals of every 10 to 20 meters of cable length.

This surge arrester is designed to coordinate with the Class 1 EX9UE1 35 line, achieving this coordination through the use of a 10-meter cable. Its construction uses varistor elements, known for their low response time to voltage spikes, ensuring quick protection against electrical surges. With a modular design, the surge arrester allows for the replaceable insert, making it easy and efficient to replace functional modules if they burn out due to frequent overvoltage occurrences. The 1+N pole configuration ensures compatibility with a wide range of electrical systems. The product's EAN is 8592765033505.
