Surge limiter insert type V25-B+C 0-280 5097053

Surge protection for your installation

This surge limiter insert, designated V25-B+C, is a key element ensuring electrical safety in buildings and installations. Designed to work with class 1+2 surge limiters, it effectively protects against the effects of voltage surges caused by lightning strikes or other disturbances in the network. Its compact size – only 1 module – makes it easy to install even in crowded distribution boards.

Construction and application

This insert is designed for mounting on a base, ensuring stability and ease of replacement. Its main task is to limit overvoltages to a safe level, protecting connected devices from damage. Thanks to the integrated protection, after exceeding the impulse current of 7 kA, the insert signals the need for replacement with an optical indicator. This allows for a quick response and maintaining continuous protection. It is compatible with various network configurations: TN, TN-C, TN-S, TT and TN-C-S, making it a universal solution for most installations.

Key features and benefits

• Versatility: The ability to use in various network configurations (TN, TN-C, TN-S, TT, TN-C-S) provides a wide range of applications.
• High efficiency: Protection level of 20 kV (L-N and N-PE) and 20 kV (L-PE) guarantees effective protection against overvoltages.
• Easy diagnostics: Optical damage indication facilitates identification of the need to replace the insert.
• Compact dimensions: Occupies only 1 module in the distribution board, saving valuable space.
• High conductivity: Ensures minimal voltage drop and effective protection without disrupting the operation of devices.
• Adaptation to large wire cross-sections: Support for conductors with a maximum cross-section of 35 mm² (solid/stranded) and 352 mm² (flexible) allows connection of both standard cables and wires with a larger diameter.
• Protection against damage: Protects the circuit against overload and short circuit - like most circuit breakers in this class.
• Safety: Rated voltage AC 230V and maximum continuous operating voltage AC 280V ensure safe operation of the device in standard network conditions.

By choosing this surge-limiting insert, you are investing in long-term protection of your electrical installation and connected devices. This provides peace of mind and minimizes the risk of costly failures caused by overvoltages.
