## Long description

Circuit breaker Legrand LE-403358 single-phase 20A Type B is a single-pole protection device designed for residential and light commercial electrical installations. It provides overcurrent and short-circuit protection for single-phase circuits, combining a compact DIN-rail mountable design with a Type B tripping characteristic suitable for general-purpose branch circuits. The device is intended for integration into distribution boards where stable, repeatable disconnection of faulty circuits is required.
Advantages
The compact form factor facilitates installation in crowded distribution panels while maintaining clear labeling and terminal access. The Type B characteristic ensures predictable tripping behavior on moderate fault currents and protects sensitive downstream devices from overload. Legrand manufacturing and standardized mounting make the breaker compatible with common DIN-rail systems and distribution board layouts.
Suitable for
Protection of lighting and socket circuits in residential buildings
Small commercial premises with single-phase supplies
Branch circuit protection for appliances with low inrush currents
Upgrades or replacements in existing DIN-rail distribution boards
Key specifications
Rated current: 20 A
Poles: single-pole (single-phase)
Tripping characteristic: Type B
Mounting: DIN-rail compatible
Primary function: overcurrent and short-circuit protection
How to use
Install the breaker on a standard DIN-rail inside the distribution board following applicable electrical codes and safety procedures. Connect the supply conductor to the line terminal and the outgoing circuit conductor to the load terminal, ensuring secure torque on terminal screws and correct polarity. After installation, test the breaker by applying normal load and verifying that the device remains closed, then simulate a fault condition or use a test procedure to confirm tripping operation. Label the protected circuit clearly on the distribution board for future maintenance.
Usage recommendations
Select this 20A Type B breaker for general-purpose branch circuits where moderate inrush currents are expected and where sensitive equipment requires stable disconnection characteristics. Ensure coordination with upstream protective devices and observe cable sizing and ambient temperature derating to maintain reliable protection.
