Product information

Description

The Legrand TX3 403397 is a high-quality 3-pole miniature circuit breaker engineered to provide robust electrical protection in various distribution systems. Designed for precision and safety, this device effectively monitors electrical circuits to prevent damage from overloads and short circuits. With a rated current of 4A and a breaking capacity of 6kA, it serves as a reliable component for maintaining the integrity of electrical installations in both residential and commercial environments.

Advantages

This circuit breaker offers exceptional reliability and durability, consistent with the high standards of Legrand engineering. Its Type B tripping characteristic ensures rapid response to fault conditions, providing enhanced protection for sensitive equipment and wiring. The compact 3-pole design allows for efficient space utilization within electrical panels, while the robust construction ensures long-term operational stability under standard electrical loads.

Suitable for

Residential electrical distribution boards
Commercial building power systems
Protection of lighting circuits
General purpose low-current electrical installations

When it may not be suitable

This device is not intended for use in environments with high-inrush current loads, such as large motor starting circuits, where a Type C or D breaker would be more appropriate. It is also not suitable for outdoor installations without an additional protective enclosure, as the device is rated IP20.

Number of poles: 3
Tripping characteristic: Type B
Breaking capacity: 6kA
Operating voltage: 240-415V AC
Frequency: 50-60Hz

How to use

The Legrand TX3 circuit breaker is designed for standard DIN rail mounting within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the power supply is disconnected before mounting the device. Secure the breaker onto the DIN rail, connect the incoming supply cables to the top terminals, and connect the outgoing load cables to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque.

What to consider before purchase

Verify that the 4A rated current matches the requirements of your specific circuit.
Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
Confirm that the 3-pole configuration is compatible with your electrical system layout.
Check that the installation environment meets the IP20 protection requirements.

Usage recommendations

Always ensure that the circuit breaker is correctly sized for the connected load to prevent nuisance tripping or inadequate protection. Regularly inspect the electrical panel for signs of loose connections or thermal damage to ensure continued safe operation.
