Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/50 1+0 002440720

Electrical installation protection with ETITEC GSM T12 surge limiters

The ETITEC GSM T12 275/50 1+0 surge arrester is a reliable element protecting electrical installations from the effects of atmospheric overvoltages and disturbances. A Class 1+2 device, based on spark-gap technology, effectively protects electrical and electronic devices from damage, ensuring uninterrupted power supply. This is particularly important for sensitive receivers such as RTV equipment, computers, or automation systems.

This arrester is used in TN, TN-C and TN-S network installations, making it a universal solution for a wide range of facilities – from single-family homes to commercial buildings. Installation is carried out on a standard DIN TH-35 mm mounting rail, which simplifies and speeds up installation. The compact size (2 modules) allows for efficient use of space in the switchgear cabinet.

#### Characteristics and application

The device is characterized by high efficiency – a surge current of 50 kA and a protection level of 1.5 kV guarantee effective protection against overvoltages. The specific energy of 625 kJ/Ohm ensures the ability to absorb surge energy, minimizing the risk of damage. Optical indication of operation facilitates quick identification of the device status and possible replacement after a surge event.

The use of the ETITEC GSM T12 arrester is crucial wherever high protection against overvoltages is required – in residential, office, industrial buildings and public utility facilities. It protects not only the electrical installation itself, but also the devices connected to it, which translates into reduced repair and equipment replacement costs. Therefore, investing in a surge arrester pays off quickly.

#### Key features and benefits

* **Versatility:** Designed to operate in TN, TN-C and TN-S network systems.

• High efficiency: Surge current of 50 kA and protection level of 1.5 kV provide effective protection against overvoltages.

• Compact size: Occupies only 2 modules in the switchgear cabinet.

• Easy installation: Mounting on a standard DIN TH-35 mm rail.

• Optical signaling: Facilitates quick identification of the device status after a surge event.
