Product information

Description

The Legrand TX3 3-pole miniature circuit breaker is a high-quality electrical protection device engineered to ensure safety and reliability in demanding electrical systems. Designed for professional use, this circuit breaker provides effective protection against overloads and short circuits in three-phase installations. With a robust construction and precise tripping mechanisms, it serves as a critical component for maintaining the integrity of electrical circuits in various environments.

Advantages

This circuit breaker offers exceptional reliability due to its high-performance design and adherence to stringent safety standards. The D-type tripping characteristic makes it particularly effective for circuits with high inrush currents, such as those powering motors or transformers, preventing nuisance tripping while ensuring rapid disconnection during genuine faults. Its compact 3-pole configuration allows for efficient space utilization in distribution boards, while the durable housing provides consistent performance under standard operating conditions.

Suitable for

Industrial electrical installations
Commercial building power distribution
Protection of circuits with high inrush current loads
Motor control centers
Three-phase electrical systems

When it may not be suitable

This device is not intended for residential applications where B or C type breakers are typically required for standard lighting and socket circuits. It is also not suitable for outdoor environments without an additional protective enclosure, as the IP20 rating indicates it is not protected against water ingress or dust accumulation.

How to use

The Legrand TX3 circuit breaker is designed for mounting on a standard DIN rail within a distribution board or consumer unit. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply voltage matches the device specifications before connection. The cables should be securely fastened to the terminals to prevent overheating and ensure optimal electrical contact.

What to consider before purchase

Verify that the 2 A rated current is appropriate for the specific load requirements of your circuit.
Ensure the D-type tripping characteristic is necessary for your specific application.
Confirm that the installation environment is dry and free from excessive dust.
Check that the distribution board has sufficient space for a 3-pole device.

Usage recommendations

Always ensure the power supply is completely disconnected before attempting to install or replace the circuit breaker. Regularly inspect the device for any signs of physical damage or discoloration, and test the functionality periodically to ensure continued protection of your electrical system.
