Modular surge arrester ETITEC ML T123 300/12,5 3+0 RC 002440666

Surge protection for electrical installations

This ETITEC ML T123 300/12.5 3+0 RC modular surge protector is a key element ensuring the safety and reliability of the electrical installation. Designed for mounting on a TH-35 mm DIN rail, it offers comprehensive protection against the effects of atmospheric and switching surges. This is a Class 1+2 device, which means it effectively protects against both direct and indirect lightning strikes, as well as surges generated by the operation of devices in the network.

Construction and application

This surge protector has three poles and occupies 3 modules in the distribution board. Its construction based on MOV (Metal Oxide Varistor) technology ensures a quick and effective response to sudden voltage increases. Additionally, the presence of an optical signaling contact informs about the operation of the surge protector, which facilitates diagnostics and quick replacement of the damaged element. Designed to operate in TN and TN-C network systems, it is a universal solution for a wide range of applications – from single-family homes to industrial facilities. The maximum conductor cross-section for connection is 35 mm² for solid conductors and 25 mm² for stranded conductors, providing flexibility when selecting power cables.
