Surge arrester T1 25 KA 1P+N 412281

Protection of electrical installations against overvoltage

This Class T1 surge protector with a surge current of 25kA is a key element in protecting electrical installations in residential and commercial buildings. It provides protection against the effects of lightning strikes and other overvoltages, minimizing the risk of equipment damage and fire hazards. It is designed for mounting on a TH-35 mm DIN rail, which simplifies its integration with the existing distribution board.

Construction and application

This surge protector is designed to work with TN, TT, TN-C and TN-C-S network systems. Its T1 technology-based construction allows for a quick response to sudden voltage surges, dissipating energy to ground. The L-N and N-PE protection level of 1.5 kV guarantees effective protection against differential and common mode overvoltages. Optical signaling informs about the operation of the device, which facilitates diagnostics and a quick response in the event of a failure. The ability to connect a wire with a cross-section of up to 35 mm² makes these surge protectors suitable for both new and modernized installations.

Key features and benefits

• High protection efficiency: Surge current of 25 kA provides effective protection against strong overvoltages.
• Versatility: Compatibility with various network systems (TN, TT, TN-C, TN-C-S) increases the range of applications.
• Fast response: Class T1 guarantees a lightning-fast response to overvoltages, minimizing the risk of damage.
• Status indicator: Optical indication of operation facilitates identification of the need for replacement or repair.
• Easy installation: Mounting on a TH-35 mm DIN rail simplifies installation and integration with the existing distribution board.
• Remote signaling: The ability to connect to a remote device status monitoring system provides an additional level of security and control.
• Compact dimensions: 4 module size allows for efficient use of space in the distribution board.
• Safety: Provides protection against overvoltages for both phase (L-N) and neutral (N-PE) lines.
