Product information

Description

The Legrand TX3 403423 is a high-quality 4-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and commercial environments. This device is designed to effectively detect and interrupt overloads and short circuits, ensuring the safety of connected electrical infrastructure and equipment. With a robust construction and precise engineering, it serves as a critical component for maintaining electrical system stability.

Advantages

This circuit breaker offers reliable performance through its B-type tripping characteristic, which is optimized for standard electrical loads. The 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral, providing comprehensive isolation. Its compact design facilitates easy installation in standard distribution boards, while the 6 kA breaking capacity ensures it can handle significant fault currents safely. The device is built to meet rigorous safety standards, offering long-term durability and consistent operation.

Suitable for

Residential electrical distribution boards
Commercial building power systems
Protection of lighting and general-purpose circuits
Electrical installations requiring 4-pole isolation

When it may not be suitable

This device is not intended for use in environments with high levels of dust, moisture, or corrosive gases, as it carries an IP20 rating. It is also not suitable for applications requiring a different tripping characteristic, such as C or D types, which are necessary for high-inrush current equipment like large motors or transformers.

Key specifications

Rated current: 63 A
Number of poles: 4
Tripping characteristic: Type B
Breaking capacity: 6 kA
Voltage rating: 240 - 415 V AC
Frequency: 50 - 60 Hz
Protection rating: IP20
Dimensions: 88 mm x 70.8 mm x 77.8 mm

How to use

The circuit breaker should be installed by a qualified electrician in accordance with local electrical codes and regulations. It is designed for mounting onto a standard DIN rail within an electrical distribution enclosure. Ensure that all wire connections are tightened to the specified torque to prevent overheating. Once installed, the toggle switch can be used to manually open or close the circuit, while the internal mechanism will automatically trip the switch in the event of an electrical fault.

What to consider before purchase

Verify that the 63 A rated current matches your circuit requirements.
Ensure the 4-pole configuration is compatible with your electrical system layout.
Check that the available space in your distribution board accommodates the 70.8 mm width.
Confirm that the B-type tripping curve is appropriate for your specific load types.

Usage recommendations

Always inspect the device for any physical damage before installation. Ensure that the electrical system is de-energized during the installation process to prevent accidental contact with live parts. Periodically check the terminal connections to ensure they remain secure over time.
