## Long description

Legrand surge arrester insert B+C 8 kA 320 V model 412302 is a compact protective module designed to reduce transient overvoltages in low-voltage electrical installations. Intended for installation in modular distribution boards, this insert combines Class B and Class C protection levels to limit high-energy surges and residual overvoltages, helping to protect connected equipment from lightning-induced and switching transients while maintaining compatibility with standard DIN-rail mounting systems.
Advantages
The module provides combined B+C protection in a single insert, offering a balance between high-energy surge handling and downstream voltage limitation. With a nominal discharge current capacity of up to 8 kA, it addresses typical surge events in residential and commercial supply networks. Its compact, modular form factor allows straightforward integration into existing distribution boards without requiring extra enclosure space or complex wiring changes.
Suitable for
Residential distribution boards to protect household appliances and electronics
Small commercial and office electrical panels
Protection of sensitive loads such as telecom equipment, routers, and small servers
Installations where combined Class B and C surge protection is required
Key specifications
Type of protection: combined B+C surge protection
Nominal discharge current capacity: up to 8 kA (per specified testing standard)
Rated voltage: 320 V
Modular form factor suitable for DIN-rail or similar modular mounting systems
Intended application: protection of low-voltage distribution circuits against transient overvoltages
How to use
Mount the surge arrester insert in a compatible modular distribution board according to local electrical regulations and the distribution board manufacturer’s instructions. Ensure the device is installed at the service entrance or upstream of the circuits and loads you intend to protect to maximize effectiveness.
