Surge arrester T1+T2 12.5/60 3P+N 412277

Electrical installation protection with Legrand ON300 surge protectors

The ON300 series T1+T2 surge protector is a key element in protecting electrical installations from the effects of lightning strikes and surges. The device effectively protects against damage to electrical and electronic equipment, minimizing the risk of failure and ensuring uninterrupted power supply. The 3P+N model with a surge current of 12.5 kA is designed for use in three-phase installations, offering comprehensive protection in both residential and commercial buildings.

Construction and application

This surge protector combines the features of a Type T1 protector (protection against direct lightning strikes) and a Type T2 protector (protection against indirect surges). Mounting is done on a standard TH-35 mm DIN rail, which simplifies integration with the existing distribution board. Optical indication of the device status informs about its operation, enabling quick identification of any problems. Designed to work with TN-C, TN-S, TT and TN-C-S network systems. Integrated remote signaling contact allows connection to monitoring and alarm systems.

Key features and benefits

• Versatile protection: The combination of class T1 and T2 provides comprehensive protection against various types of surges.
• High efficiency: Surge current of 25 kA guarantees effective protection even during strong lightning strikes.
• Universality: Compatibility with different network systems (TN-C, TN-S, TT, TN-C-S) increases the range of applications.
• Easy installation: Standard mounting on a TH-35 mm DIN rail simplifies installation and replacement.
• Feedback: Optical indication of operation facilitates diagnostics and maintenance.
• Remote signaling: The ability to connect to monitoring systems provides an additional level of security.
• Solid construction: Made of high-quality materials guarantees durability and reliable operation.
• Adapted for large diameter cables: The maximum cross-section of the flexible conductor is 25 mm², and the rigid one is 35 mm².

This surge protector is an ideal solution for installers looking for a reliable and easy-to-install protective device, and for end-users who value the safety of their electrical equipment.
