This compact unit ensures reliable performance and safety in various electrical distribution systems, maintaining consistent power flow while reacting promptly to electrical faults.

Advantages

This circuit breaker offers exceptional reliability and durability, characteristic of the Legrand brand.

Suitable for

Residential lighting circuits
General-purpose power outlets
Small commercial electrical installations
Protection of sensitive electronic equipment with low inrush currents

This device may not be suitable for circuits with high inrush currents, such as those powering large motors, transformers, or heavy industrial machinery, where a Type C or Type D breaker would be required to prevent nuisance tripping.

How to use

The circuit breaker is designed for mounting on a standard DIN rail within an electrical distribution board.

Secure the device firmly onto the rail and connect the supply and load cables to the appropriate terminals, ensuring all connections are tightened to the manufacturer's specified torque.

What to consider before purchase

Verify that the 4A rating is appropriate for the specific load of your circuit.
Ensure the Type B characteristic matches the requirements of your connected appliances.
Check the available space in your distribution board for a 17.8 mm wide module.
Confirm that the installation environment is dry and protected, as the unit is rated IP20.
