We also carry numerous products from Legrand's industrial circuit breaker range.

Understanding the Role of Fuse-Holder Disconnectors

What exactly is a fuse-holder disconnector? Simply put, it's not just a conventional switch or circuit breaker! It's a 2-in-1 electrical device that combines two functions. First, the isolation function: the fuse-holder allows you to completely disconnect a circuit so that you can work safely on your electrical installation. It also provides fuse protection: thanks to its cylindrical cartridge or integrated blade fuse, it effectively protects against overloads and short circuits.

Please note: unlike standard thermal-magnetic circuit breakers, some fuse-holder disconnectors can only be operated when the power is off. This is because the DF models cannot be used to cut a circuit under load, while GS models can. This distinction is crucial for the safety and service life of your electrical equipment.

Switch Configuration: Single-Pole, Double-Pole, or Four-Pole?

How do you choose from all these fuse-holder disconnectors? It all depends on your electrical installation!

You mainly have the following options:

• Single-pole fuse-holder: only cuts the phase, ideal for simple residential applications
• Double-pole fuse-holder: for circuits requiring both phase and neutral or two phases to be cut
• Three-pole fuse-holder: for three-phase installations without neutral
• Four-pole fuse-holder: ideal for industrial use, acting simultaneously on three phases + neutral

At One-Elec, we offer the full range of Schneider Electric (including the Tesys and Acti 9 ranges) and Legrand fuse-holder disconnectors. Our detailed technical data sheets will help you make the right choice for your disconnector circuit.

How to Choose According to Amperage and Fuse Type?

Amperage and fuse size are THE critical factors that determine which fuse-holder to choose. Here's how to find your way around:

First, assess the power requirements of your installation. A fuse-holder that's too small will overheat and compromise the protection of your circuit. A model that's too large? That's an unnecessary investment!

There are two main types of fuses to consider. First, there are cylindrical fuses, which are the most common for residential and commercial installations and are available in different sizes. Then there's the knife fuse family, designed for industrial environments and high-power applications.

The Schneider fuse or Acti STI fuse you choose must correspond precisely to the rating of your fuse holder and the current of your circuit. An incorrectly sized fuse holder compromises your entire electrical installation.

Don't forget: all our fuse holders offer IP20 protection against direct contact, but be sure to check the maximum rated voltage supported by your device. This varies depending on the model and application!

How to Choose the Right Fuse-Holder Disconnector?

Here are the essential criteria to consider when choosing your fuse-holder disconnector:

• The number of poles: single-pole + neutral, double-pole, triple-pole, or quadruple-pole - choose the right configuration for your installation
• The operating voltage: a crucial parameter for compatibility with your electrical network
• Maximum current rating: determines the capacity of your fuse-holder disconnector to handle loads
• Type of compatible fuses: cylindrical fuses or blade fuses, depending on the fuse size required
• Number of pre-break contacts: important for the opening sequence of your disconnector
• Accessories: type of control, DIN rail mounting system, lockout device to secure your fuse-holder

Our detailed technical data sheets will help you select the perfect fuse-holder for your switching circuit.

Fuse-Holder Accessories: Optimize Your Installation

Fuse-holder accessories are not optional! They significantly improve the functionality and safety of your installation:

• Fuse drawer: facilitates cartridge replacement without special tools
• Lockable handles: prevent unauthorized manipulation during maintenance operations
• Voltage indicator lights: instantly indicate whether a circuit is live
• Auxiliary contacts: allow you to monitor the status of your fuse-holder disconnector remotely
• DIN rail adapters: for seamless integration into your electrical enclosures
