Modular surge arrester ETITEC ML T123 300/12,5 3+0 002440665

Electrical installation protection with ETITEC ML T123

ETITEC ML T123 300/12.5 3+0 modular surge protector is a reliable device designed to protect electrical installations from the effects of overvoltages, both those caused by lightning strikes and disturbances in the network. It provides Type 1, Type 2 and Type 3 protection, making it a universal solution for various applications. Mounting is done on a standard DIN TH-35 mm rail, which facilitates integration with existing switchboards.

Functionality and application

This surge protector protects against overvoltages resulting from direct and indirect lightning strikes and switching surges. The surge current level of 12.5 kA guarantees effective protection even in the event of strong disturbances. The three-pole design (3P) is ideal for protecting single-phase circuits with a PE protective conductor. The specific energy level of 39 kJ/Ohm demonstrates its ability to absorb large energy impulses. The device is designed to operate in TN and TN-C network systems.

Construction and characteristics

The ETITEC ML T123 surge protector occupies 3 modules in the switchboard, allowing for easy placement even in limited space. It has optical indication of operation, which informs about the need to replace the module after a surge. Made of high-quality varistors, it ensures long-lasting and reliable operation. The maximum wire cross-section for connection is 35 mm² for solid and stranded wires and 25 mm² for flexible wires, providing great flexibility during installation. Protection class Type 1+2 provides comprehensive protection against various types of overvoltages. The degree of protection IP20 guarantees safe use in standard environmental conditions.
