Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 440/35 1+0 002440716

Surge protection for your installation

The ETITEC GSM T12 440/35 1+0 surge arrester is a reliable element protecting the electrical installation from the effects of current surges and overvoltages. Designed to work with TN, IT, TN-S and TN-C networks, it is a key element in protecting electrical and electronic devices. Its design based on spark-gap technology ensures a quick response to sudden voltage increases.

Construction and application

The arrester is designed for mounting on a TH-35 mm DIN rail, taking up only 2 modules. This makes it ideal for both distribution boards in residential buildings and industrial facilities. Protection class Type 1+2 (B+C) guarantees comprehensive protection against overvoltages of various origins – both internal (e.g. generated by devices in the building) and external (e.g. caused by lightning strikes). Optical indication of operation makes it easy to identify a situation where the arrester has reacted to an overvoltage.

Key features and benefits

• High efficiency: Surge current 35 kA and protection level 2.5 kV provide effective protection against damage caused by overvoltages.
• Versatility: Compatibility with various network systems (TN, IT, TN-S, TN-C) allows it to be used in a wide range of electrical installations.
• Compact dimensions: Occupies only 2 modules on the DIN rail, making it easy to install even in limited space.
• Durability: Follow current extinguishing capacity up to 100 kA guarantees safe operation in the event of a short circuit.
• Safety: Optical indication of operation informs about the need to replace the arrester after a strong overvoltage occurs.
• Large cross-section wires: Supports flexible wires with a cross-section of up to 25 mm² and rigid/stranded wires up to 35 mm².
• Energy consumption: Specific energy at the level of 306.25 kJ/Ohm indicates a high ability to absorb energy during overvoltages.

Using this arrester is an investment in the safety and reliability of the electrical installation, protecting valuable equipment from damage and minimizing the risk of downtime.
