Surge arrester T1+T2 12.5/60 2P 412271

Protection of electrical installations and devices

A T1+T2 surge protector is a key element in protecting electrical installations from the effects of lightning strikes and fast voltage transients. This model, with a rated discharge current of 25 kA, provides comprehensive protection in TN, TN-S and TN-C-S networks. Its design combines the features of a Type 1 (T1) and Type 2 (T2) surge protector, meaning it effectively responds to both direct lightning strikes and disturbances caused by switching loads.

Construction and mounting

Designed for mounting on a DIN TH-35 mm mounting rail, it occupies only 2 module widths, allowing for easy placement in a distribution box. It accepts wires with a cross-section of up to 35 mm², ensuring compatibility with most standard installations. The surge protector has optical indication of operation, which informs about the need for replacement after a surge occurs. It should be noted that the device does not have remote signaling or built-in additional protection.

Application and benefits

This surge protector is ideal for protecting electrical circuits powering sensitive electronic devices such as RTV equipment, computers and home automation systems. The protection level of 1.9 kV guarantees effective voltage reduction to a safe level. This minimizes the risk of damage to connected devices and downtime of the installation. The degree of protection IP20 provides basic protection against accidental contact. The device is designed to operate in networks with a rated voltage of 230 V and a maximum continuous AC operating voltage of 320 V.
