Product information

Description

The Legrand 412903 is a high-quality 2-pole modular changeover switch designed for precise electrical circuit control. This device enables efficient switching between two distinct power sources or circuits, providing a reliable solution for power management in both residential and commercial electrical distribution boards. Engineered for standard DIN rail mounting, it ensures a secure fit and consistent performance within your electrical infrastructure.

Advantages

This modular changeover switch offers exceptional reliability and safety, adhering to international standards for electrical equipment. Its compact design allows for space-efficient installation in distribution panels, while the 32A rating ensures it can handle demanding electrical loads. The switch is specifically designed to be compatible with fluorescent lamps, making it a versatile choice for various lighting and power control applications.

Suitable for

Switching between main power and backup generator sources
Manual control of two separate electrical circuits
Integration into residential distribution boards
Commercial power management systems
Control of fluorescent lighting circuits

When it may not be suitable

This device is not intended for applications requiring automatic transfer switching, as it is a manual changeover switch. It is also not suitable for high-voltage industrial systems exceeding its 400V rating or for environments where the current load consistently exceeds 32A.

Key specifications

Number of poles: 2
Nominal current rating: 32 A
Voltage rating: 400 V
Mounting type: DIN rail
Number of modules: 2
Compliance: IEC 60669-1
Fluorescent lamp compatibility: 20 AX

How to use

The switch is designed for installation by qualified personnel within a standard electrical distribution board on a DIN rail. Once mounted, the switch provides a manual I-0-II operation, allowing the user to select between two power sources or to disconnect the circuit entirely in the central '0' position. Ensure all connections are tightened according to the manufacturer's specifications to maintain electrical safety.

What to consider before purchase

Verify that your electrical system requires a 2-pole configuration
Ensure the 32A rating is sufficient for your specific load requirements
Check available space in your distribution board for a 2-module wide device
Confirm compatibility with your existing DIN rail setup

Usage recommendations

Always ensure that the power supply is disconnected before attempting to install or perform maintenance on the switch. Regularly inspect the connections to ensure they remain secure and free from oxidation to maintain optimal performance.
