Modular surge arrester ETITEC ML T123 300/12,5 1+0 RC 002440662

Modular surge protector – reliable installation protection

This ETITEC ML T123 300/12.5 1+0 RC modular surge protector is a key element ensuring electrical safety in residential and commercial buildings. 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 electrical appliances.

Functionality and application

This surge protector is designed to protect electrical installations with a rated voltage of 240V and a maximum continuous operating voltage of 300V. Its construction based on MOV (Metal Oxide Varistor) technology ensures a quick and effective response to sudden voltage increases. The surge current level of 12.5 kA guarantees effective protection even in the event of strong discharges. Additionally, an optical indicator signals the device's status – red indicates damage, and green – correct operation. This makes it easy to check whether the surge protector is still functioning properly.

Key features and benefits

• Versatile protection: Protection class Type 1+2 provides protection against various types of surges.
• Status indication: Optical damage indicator facilitates diagnostics and quick replacement if necessary.
• Compatibility with various network systems: The device works with TN, TN-C and TN-S systems, increasing its versatility.
• Large wire cross-section: Support for wires with a cross-section of up to 35 mm² (solid) and 25 mm² (stranded) allows connection of both smaller and larger installations.
• Energy absorption: Specific energy at 39 kJ/Ohm indicates the ability to absorb large surge energies without damage.
• Safety: It has internal thermal protection that disconnects the device in case of overheating, minimizing the risk of fire or failure.
• Easy installation: Mounting on a TH-35 mm DIN rail is quick and easy, saving time during installation.
• Remote signaling: RC module enables remote monitoring of the surge protector status.

The ETITEC ML T123 surge protector is a solid solution for installers looking for reliable surge protection and for end users who value the safety of their electrical appliances. Its compact size (1 module) allows for easy adaptation to an existing distribution board.
