Product information

Description

The Legrand TX3 403439 is a high-quality single-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in various environments. Designed for efficiency and safety, this device effectively manages power distribution by interrupting current flow during overloads or short circuits. Its robust construction ensures consistent performance in both residential and commercial electrical installations, maintaining the integrity of your power network.

Advantages

This circuit breaker offers exceptional reliability and durability, meeting stringent safety standards for electrical protection. Its compact design allows for space-saving installation within standard distribution boards, while the Type C tripping characteristic provides a balanced response to current surges, making it ideal for circuits with moderate inrush currents. The device is built to withstand standard operational demands, ensuring long-term stability and protection for connected equipment.

Suitable for

Residential electrical distribution boards
Commercial power management systems
Protection of lighting and general-purpose circuits
Installations requiring a 50A rated current capacity

When it may not be suitable

This device is not intended for use in environments with high moisture or dust levels, as it carries an IP20 rating and lacks specialized weatherproofing. It is also not suitable for applications requiring multi-pole protection, as this is a single-pole unit.

Rated current: 50 A
Number of poles: 1
Tripping characteristic: Type C
Voltage range: 240 - 415 V

How to use

The Legrand TX3 circuit breaker is designed for mounting on a standard DIN rail within an electrical distribution panel. Installation should be performed by a qualified electrician to ensure all connections are secure and compliant with local electrical codes. Once installed, the toggle switch allows for manual control of the circuit, and the device will automatically trip to the off position in the event of an electrical fault.

What to consider before purchase

Ensure the 50A rating matches your circuit requirements
Verify that your distribution board has sufficient space for a single-module width
Confirm that a single-pole breaker is appropriate for your specific wiring configuration
Check that the operating voltage is within the 240-415 V range

Usage recommendations

Always ensure the power supply is disconnected before attempting any installation or maintenance work on the electrical panel. Regularly inspect the circuit breaker for signs of wear or damage to maintain optimal safety levels.
