Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/25 3+1 RC 002440611

Electrical installation protection with ETITEC GSM T12 surge limiters

The ETITEC GSM T12 275/25 3+1 RC surge limiter is a reliable element protecting the electrical installation from the effects of atmospheric overvoltages and network disturbances. Designed to work with TT and TN-S systems, it effectively protects electrical devices, ensuring their long-term and trouble-free operation. The construction based on Class T1 and T2 spark gaps (B, C) guarantees a quick response to sudden voltage increases, minimizing the risk of damage.

Construction and application

The limiter is designed for mounting on a TH-35 mm DIN rail, occupying 4 modules. This compact solution is ideal for both home and commercial installations. It has an optical indication of operation, which facilitates the identification of an emergency situation. Equipped with a signaling contact, it enables remote monitoring of the device status. The wire cross-section up to 35 mm² allows connection of a wide range of flexible (up to 25 mm²) and rigid wires.

Key features and benefits

• Versatility: Compatible with TT, TN-S and TN network systems.
• High efficiency: Impact current of 25 kA and specific energy of 156.2 kJ/Ohm provide effective protection against overvoltages.
• Protection levels: Provides a protection level of 1.5 kV for L-N and N-PE, as well as 1.55 kV overall.
• Status indication: Optical indication of operation and signaling contact facilitate diagnostics and servicing.
• Safety: The ability to extinguish the follow current at a level of 50 kA minimizes the risk of electric arc formation after the limiter has operated.
• Mounting: Quick and easy mounting on a TH-35 mm DIN rail – saving time during installation.
• Universality: Suitable for protecting various receivers, including devices sensitive to overvoltages, such as RTV, household appliances or alarm systems.

The ETITEC GSM T12 limiter is an investment in the safety of your electrical installation and connected devices – solid protection against the effects of unforeseen events in the power grid.
