How to Choose the Right Legrand Disconnect Switch
The selection of the appropriate disconnect switch model is based on several essential technical criteria:
- Power: The rating of the disconnect switch must exceed the maximum current of the protected circuit. A safety factor of 20% is recommended.
- Type of installation: Modular on DIN rail, surface-mounted, or flush-mounted depending on your installation configuration.
- Rated voltage: Check compatibility with your electrical network (typically 230V single-phase or 400V three-phase).
- Number of poles: From 1 to 4 depending on whether you want to disconnect only the phase or the phase(s) and neutral.
Compliance with electrical standards requires specific installation procedures. Please refer to our technical data sheets for more details. Any questions? Specific requirements? Our technical expert is available to assist you!
FAQ – Frequently Asked Questions About Disconnect Switches
What is the difference between a disconnect switch and a disconnector? A disconnect switch can be operated under load, unlike a simple disconnector, which requires the power to be cut off first. Legrand disconnect switches therefore combine two essential functions.
Is it possible to operate a disconnect switch when it is under load? Yes, this is precisely the main function of a disconnect switch. Unlike a simple isolator, it is designed to withstand the electric arc that forms when the load is disconnected.
What power rating should I choose for my disconnect switch? Calculate the maximum current of your circuit and then select a higher rating. For a standard domestic installation, a 63A Legrand disconnect switch is generally suitable. Larger installations require higher ratings.
How do I install a Legrand disconnect switch? Installation must be carried out by a qualified electrician. Installation varies depending on the model: DIN rail mounting for modular versions, direct screw mounting for surface-mounted models. Always follow the connection diagrams provided.
What is the difference between a circuit breaker, a switch, and a disconnector? A circuit breaker protects against overloads and short circuits. A switch allows the load to be turned off without protection. A disconnector isolates but must not be operated under load. A disconnect switch combines the functions of a switch and a disconnector.
