Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/25 1+0 002440600

Electrical installation protection with ETITEC GSM T12

The ETITEC GSM T12 275/25 1+0 surge protector is a reliable device that protects electrical installations from the effects of atmospheric overvoltages and network disturbances. It is a key element of protection for electrical and electronic devices, especially those sensitive to sudden voltage changes. The design based on spark-gap technology ensures a quick response and effective dissipation of surge pulse energy.

This surge protector, with protection class Type 1+2, is ideal for TN, TN-S and TN-C networks. Its compact size – only 1 module – allows for easy mounting on a TH-35 mm DIN rail, saving valuable space in the distribution board. Optical signaling of the device status facilitates quick identification of any failures.

Key features and parameters

The device is characterized by high efficiency, confirmed by parameters such as a surge current of 25 kA (10/350 µs) and a follow current extinguishing capability of 50 kA. The protection level of 1.55 kV guarantees effective protection against overvoltages. The energy efficiency of the device is 156.2 kJ/Ohm, which demonstrates its ability to absorb large energy pulses.

• Versatility: Designed for TN, TN-S and TN-C networks – ideal for most typical installations.
• Compactness: Occupies only 1 module on the DIN rail, making it easy to install even in crowded distribution boards.
• High efficiency: Surge current of 25 kA and follow current extinguishing capability of 50 kA provide solid protection.
• Optical signaling: Enables quick visual control of the device status and any failures.
• Universal conductors: Supports conductors with a cross-section of up to 35 mm² (stranded) and 25 mm² (flexible).
• Safety: Complies with standards regarding overvoltage protection.

Installation and application

Installation of the ETITEC GSM T12 surge protector is simple and intuitive – just mount it on a standard TH-35 mm DIN rail. The device is used to protect electrical installations in residential, commercial and industrial buildings. It is particularly recommended for protecting electronic devices such as televisions, computers, audio-video equipment, and alarm and monitoring systems. Thanks to its reliability and effectiveness, it is an investment in the safety and long-term efficiency of the electrical installation.
