Modular surge arrester ETITEC ML T123 300/12,5 4+0 002440667

Protection of electrical installations against overvoltage

The ETITEC ML T123 300/12.5 4+0 modular surge protector is a reliable device designed to protect electrical installations from the effects of lightning strikes and switching surges. It provides comprehensive Type 1, Type 2 and Type 3 protection (class B, C, D), making it a universal solution for both new and modernized installations. Mounted on a TH-35 mm DIN rail, it is ideal for main distribution boards.

Construction and application

This surge protector is designed to protect against overvoltages in TN and TN-S network systems. Its varistor-based design guarantees effective interference suppression and minimizes the risk of damage to connected devices. Four poles provide complete circuit protection, and the compact size – only 4 modules – makes it easy to install even in crowded distribution boards. Optical signaling informs about any device operation, allowing for quick problem identification.
