Legrand 406431 Modular Switch Disconnector 16A 2P

The Legrand 406431 is a high-quality 2-pole modular switch disconnector engineered for precise and reliable control of electrical circuits. Designed to handle a rated current of 16A, this device serves as an essential component in both residential and industrial electrical distribution systems. Its primary function is to provide a secure and visible disconnection of power, ensuring safety during routine maintenance, system upgrades, or emergency shutdowns. The unit features a compact, modular architecture that facilitates straightforward installation on standard DIN rails, making it an ideal choice for modern electrical distribution boards.

Advantages

This switch disconnector offers exceptional reliability and durability, consistent with the high manufacturing standards of Legrand. Its modular design allows for seamless integration into existing electrical panels, saving valuable space and simplifying the wiring process. By providing a clear physical break in the circuit, it enhances operational safety for technicians and end-users alike. The robust construction ensures long-term performance even in demanding environments, while the 2-pole configuration provides effective isolation for single-phase circuits.

Suitable for

• Residential electrical distribution boards
• Industrial control panels
• Commercial building power management
• Isolation of lighting or small appliance circuits

This device may not be suitable for applications requiring high-power switching beyond its 16A rated current capacity. It is not intended for use as a circuit breaker for overload or short-circuit protection, as it does not contain internal tripping mechanisms for such faults.

Key specifications

• Rated current: 16A
• Number of poles: 2
• Mounting type: DIN rail
• Design: Modular

To install the Legrand 406431, ensure the power supply is completely disconnected from the distribution board. Snap the device onto the standard DIN rail within the enclosure. Connect the incoming and outgoing conductors to the appropriate terminals, ensuring that all screws are tightened to the manufacturer's specified torque to prevent overheating. Once installed, verify the connections before restoring power to the circuit.

What to consider before purchase

• Verify that the 16A rating is sufficient for your specific load requirements.
• Ensure there is adequate space on the DIN rail within your distribution board.
• Confirm that a 2-pole configuration meets the isolation needs of your circuit.

Always consult with a qualified electrician when installing or modifying electrical distribution equipment to ensure compliance with local safety regulations and standards.
