Surge protection device T2 (C) ETITEC C T2 275/20 1+1 002440401

Electrical installation protection with ETITEC C T2 surge arrestors

ETITEC C T2 275/20 1+1 surge arrester is a key element in protecting the electrical installation from the effects of overvoltages, both resulting from lightning strikes and fast transients in the network. The device is designed for mounting on a TH-35 mm DIN rail and occupies 2 modules, allowing for easy placement in a distribution board. It provides protection in TN and TT network systems, making it a universal solution for a wide range of applications.

Construction and application

This surge arrester belongs to class T2, which means it is designed to protect against the indirect effects of lightning strikes and overvoltages generated by devices inside the building. Its task is to dissipate excess energy to ground, protecting connected devices from damage. A built-in optical indicator informs about the operation of the arrester, facilitating diagnosis and rapid response in the event of an overvoltage. The construction based on varistor technology guarantees reliable operation and long service life.

Key features and benefits

• High protection efficiency: Rated discharge current of 20 kA (8/20 μs) provides effective protection against overvoltages with high energy.
• Versatility: Designed to operate in TN and TT network systems, increasing its range of applications.
• Easy installation: Mounting on a standard TH-35 mm DIN rail simplifies and speeds up installation.
• Compact dimensions: Occupies only 2 modules, allowing you to save space in the distribution board.
• Optical indicator: Informs about the operation of the arrester, facilitating diagnostics and maintenance.
• Wide range of wires: Supports wires with a cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible), ensuring compatibility with various types of installations.
• Protection level 1.5 kV: Provides a high level of protection against overvoltages, minimizing the risk of damage to connected devices.
• Rated voltage AC 230 V: Adapted to standard electrical networks.

The ETITEC C T2 surge arrester is a reliable solution for anyone who cares about the safety of their electrical installation and protects their devices from the effects of overvoltages. Its versatility and ease of installation make it an ideal choice for both professional installers and end-users looking for effective protection for their home or business.
