Surge arrester T2 12 kA 1P+N with internal protection 003951

Electrical installation protection with Legrand surge protectors

This T2 surge protector, with a surge current of 10 kA, is a key element in protecting electrical installations in residential and commercial buildings. Designed by Legrand, a renowned manufacturer of electrical solutions, it provides effective protection against the effects of lightning strikes and voltage surges in the network. Installing this device is an investment in the safety of equipment and user comfort.

This surge protector is designed for mounting on a TH-35 mm DIN rail and occupies 2 modules, allowing for easy placement in a distribution board. Its 1P+N construction makes it ideal for protecting single-phase circuits with a neutral wire. The built-in internal protection protects against overload and short circuit, increasing the reliability of the entire system.

Key features and application

• Overvoltage protection: effectively limits the voltage to a safe level during a surge, protecting connected devices.
• Versatility: operates in various network configurations – TN, TN-C, TN-C-S and TT – making it a universal solution for most installations.
• Optical signaling: an LED indicates the need to check the device status and possible replacement in case of surge protector operation.
• Mounting: easy mounting on a standard TH-35 mm DIN rail – saving time and installation costs.
• Wire cross-section: supports wires with a cross-section of up to 16 mm², ensuring compatibility with most wiring.
• Internal protection: an additional layer of protection against damage caused by overload or short circuit.

This surge protector is used to protect lighting circuits, socket outlets and electronic devices sensitive to surges, such as televisions, computers and audio-video equipment. This ensures the continuity of operation of devices and minimizes the risk of costly failures. The protection level of 1 kV and 1.2 kV guarantees a high degree of safety for connected receivers.
