Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/25 4+0 002440608
Surge protection in electrical installations
The ETITEC GSM T12 275/25 4+0 surge arrester is a reliable device that protects electrical installations from the effects of atmospheric and switching surges. Its spark-gap technology provides a quick and effective response to sudden voltage increases, minimizing the risk of damage to connected devices. This solution is ideal for both TN and TN-S network installations.
Functionality and application
This arrester is classified as type 1+2, which means it provides protection against both direct and indirect lightning strikes. A surge current of 25 kA and a protection level of 1.55 kV guarantee high efficiency in discharging surge energy to the ground. This protects sensitive electronic devices such as RTV equipment, computers, and alarm systems. Mounting on a TH-35 mm DIN rail makes it easy to integrate with existing electrical infrastructure.
Key features and benefits
Versatility: Designed to operate in TN and TN-S networks, making it a universal solution for different types of installations.
High efficiency: Surge current of 25 kA and protection level of 1.55 kV provide effective protection against surges.
Fast response: Spark-gap technology guarantees a lightning-fast response to sudden voltage increases.
Optical indicator: Has an optical indication of operation, which makes it easier to identify damage and the need for replacement.
Large wire capacity: Supports wires with a cross-section of up to 35 mm², allowing connection to most standard electrical installations.
Energy absorption: Specific energy at 156.2 kJ/Ohm indicates a high ability to absorb surge energy.
Compact size: Occupies only 4 modules on the DIN rail, saving space in the distribution board.
Follow current extinguishing capacity: At 50 kA, it ensures safety after the arrester has operated.
The ETITEC GSM T12 arrester is a solid and effective solution for anyone who cares about the safety of their electrical installation and protects valuable devices from damage caused by surges.
