Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/25 1+0 RC 002440601

Protection of installations and devices – surge protector ETITEC GSM T12

This surge protector, class T1+T2, also known as a spark gap, is a key element in protecting electrical installations from the effects of lightning strikes and surges. Designed to work with TN, TN-S and TN-C networks, it effectively protects electrical and electronic devices from damage caused by sudden voltage increases. Its compact size – only 1 module – makes it easy to install in distribution boards.

The ETITEC GSM T12 surge protector is not only protection, but also information about potential danger. It has optical indication of operation, which informs about the need to check the device status after a surge. Additionally, the presence of a signaling contact allows for remote monitoring of the surge protector status and integration with alarm or building management systems.

Construction and practical application

The surge protector is based on spark gap technology, which ensures a fast response to impulse overvoltages. An impulse current level of 25 kA and a follow current extinguishing capacity of 50 kA guarantee effective protection even in the event of strong discharges. Rated AC voltage of 230 V and maximum continuous operating voltage of 275 V make it an ideal solution for standard electrical installations in residential and commercial buildings. The ability to connect wires with a cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible) ensures compatibility with various types of cabling.

The surge protector is mounted on a standard DIN TH-35 mm mounting rail, which greatly simplifies installation. Specific energy on level 156.2 kJ/Ohm testifies to its effectiveness in absorbing surge energy. Protection level of 1.55 kV minimizes the risk of damage to connected devices. This surge protector is used wherever protection against surges is required, especially in places exposed to direct lightning strikes or induced surges in power lines.
