## Long description

Legrand Ogranicznik przepięć B+C 12.5 ON300 4-pole is a compact surge protection device designed for installation in distribution boards to protect electrical installations from transient overvoltages caused by lightning or switching operations. Combining B and C class protection, the device provides coordinated multi-pole suppression and a nominal discharge capacity of 12.5 kA to reduce the risk of damage to connected equipment and wiring in residential and commercial environments.
Advantages
The 4-pole configuration ensures simultaneous protection of all conductors in a TN or TT system, minimising differential and common-mode surges. Dual-class protection (B+C) offers early-stage diversion of high-energy transients together with downstream attenuation, improving overall system resilience. The compact form factor conserves space in the distribution board and the product is designed for straightforward DIN-rail mounting and integration with standard protective devices.
Suitable for
 Residential distribution boards and main service panels
 Small commercial premises and office installations
 Protecting sensitive electronic equipment such as routers, controllers, and consumer electronics
 Coordination with downstream overcurrent protection devices in power distribution systems
Key specifications
 Protection classes: combined B and C class surge protection
 Nominal discharge current capacity: 12.5 kA (per relevant standard rating)
 Configuration: 4-pole unit for full conductor protection
 Mounting: DIN-rail compatible, compact module for distribution boards
 Intended use: protection against lightning-induced and switching overvoltages in low-voltage systems
How to use
Install the surge protector in the main or sub-distribution board on the DIN rail according to the electrical schematics and local wiring regulations. Connect each pole to the corresponding phase and neutral conductors, ensuring proper earthing of the installation to allow safe diversion of surge currents to ground. Coordinate placement and connection with upstream and downstream protective devices, such as circuit breakers and residual current devices, to maintain selectivity and ensure correct operation during transient events. Perform visual inspection and routine checks after extreme events or as part of scheduled maintenance.
Usage recommendations
Use this surge protector as part of a coordinated protection strategy: pair it with appropriate upstream lightning protection and correctly rated overcurrent devices. Verify earthing system integrity before and after installation and replace the unit if indicators or tests show loss of protective capability following a major surge event.
