Modular Disconnecting Switches

What is a Modular Disconnecting Switch?

A modular disconnecting switch serves a dual function that is essential in your electrical panel. It cuts power like a standard switch while ensuring complete electrical isolation of the circuit. It mounts on a DIN rail and is extremely easy to install thanks to its compact design. Unlike a simple disconnector, it can handle live switching operations. You can identify these devices by their front or side operating handles and their visible open/closed position indicators for enhanced safety.

The Advantages of Modular Disconnecting Switches

Why choose a modular disconnecting switch? Their visible disconnection eliminates any risk of error during maintenance work. You can immediately tell whether a circuit is energized or not. Electrical professionals particularly value this feature when working on-site.

The modular design follows standardized specifications, allowing seamless integration into any type of electrical panel. These devices typically occupy between 1 and 4 modules depending on their configuration—a major advantage when space is limited in your installation!

Our Schneider and Legrand disconnecting switches are suitable for all your projects. They're ideal for both residential and commercial applications. Use them to isolate part of your installation, protect sensitive equipment, or create zone-based general disconnection.

Choose products built to last. Our disconnecting switches withstand daily thermal and mechanical stress. Leading brands like Legrand and Schneider offer ultra-durable mechanisms that will operate efficiently for years without special maintenance.

Choosing the Right Modular Disconnecting Switch

Selecting the right disconnecting switch depends on several essential technical criteria. Here's how to make the best choice from our selection.

Current Rating: The Right Capacity for Your Needs

The current rating represents the maximum current the device can handle. For residential applications, choose models between 20A and 63A. For commercial installations, we offer ratings up to 125A or even 160A for the most demanding applications.

Pro tip: Always select a rating at least 20% higher than your circuit's maximum current. This safety margin prevents overheating and extends equipment life.

Number of Poles: Based on Your Electrical Installation

The number of poles determines which conductors are disconnected during operation:

• Two-pole models: Disconnect phase and neutral, perfect for residential installations
• Four-pole versions: Disconnect all three phases and neutral, ideal for commercial environments

Operating Voltage and Standards Compliance

All our disconnecting switches are compatible with France's 230V/400V standard. They comply with current regulations (particularly NF C 15-100 and European directives).

Legrand or Schneider Electric? Two Industry Leaders

Our catalog features the best brands in the electrical market. Discover their strengths to help guide your choice.

Legrand Modular Disconnecting Switches

Legrand offers comprehensive product lines to meet every need. The DX3 series stands out for its reliability and easy DIN rail installation. These models provide:

• High-performance switching mechanism
• Generously sized terminals for easy wiring
• Clear circuit status visualization
• Excellent thermal resistance

For added convenience, explore the Vistop range with rotary handles. These models can be locked in the open position for maximum safety during maintenance.

Schneider Electric Modular Disconnecting Switches

Schneider Electric excels with its Acti9 ISW range, which integrates perfectly into modern switchboards. These products feature:

• Robust design for exceptional durability
• Snap-action mechanism that minimizes electrical arcing
• Self-cleaning contacts that maintain performance over time

Working on demanding commercial or industrial installations? Explore the Compact INS/INV range, which combines power and compactness up to 160A.

How to Choose Between Brands?

Your choice will depend on your existing installation, preferences, and specific requirements. Our advisors are here to help you select the right configuration—don't hesitate to contact them!

Installation and Daily Use

Installing your modular disconnecting switch is straightforward. The device clips directly onto the DIN rail inside your electrical panel. For safety, we recommend having it installed by a qualified electrician.

Daily operation is intuitive thanks to the front lever. In the open position (typically down), your circuit is completely isolated. Some models even offer padlock options to prevent accidental re-energization.
