Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/50 1+0 RC 002440721

Electrical installation protection with surge limiters ETITEC GSM T12

The ETITEC GSM T12 275/50 1+0 RC surge limiter is a reliable device that protects the electrical installation from the effects of atmospheric and switching surges. Designed in protection class Type 1+2, it effectively protects against both direct and indirect lightning strikes, as well as surges generated by devices in the network. This is a key element ensuring the continuity of operation and safety of connected devices.

Functionality and application

This surge limiter is designed for use in TN, TN-S and TN-C network systems. Its versatility makes it suitable for both home installations and commercial or industrial facilities. Thanks to the possibility of mounting on a DIN TH-35 mm mounting rail, installation is quick and easy. Optical signaling of device operation informs about the need for replacement or control of the limiter's condition. An additional signaling contact enables remote monitoring of the device status.

Characteristics and parameters

The limiter is characterized by high efficiency - an impulse current of 50 kA and a specific energy of 625 kJ/Ohm guarantee protection even with strong surges. A protection level of 1.5 kV ensures effective reduction of voltage to a safe level. The follow current extinguishing capacity of 100 kA further increases the safety of use. Compact dimensions (2 modules) allow for easy adaptation to the existing switchgear cabinet. The maximum wire cross-section of 35 mm² (stranded) and 25 mm² (flexible) ensures compatibility with various types of cabling. The device has a rated voltage of AC 230 V and a maximum continuous operating voltage of AC 275 V. The degree of protection IP20 provides basic protection against touch and solid bodies.
