Product information

Description

The Legrand TX3 miniature circuit breaker is a high-quality, single-pole protection device engineered for modern electrical installations. Designed to provide reliable safety in both residential and commercial power distribution systems, this component effectively monitors electrical circuits to prevent damage from overloads and short circuits. With a robust construction and precise engineering, it serves as a critical link in maintaining the integrity and safety of your electrical infrastructure.

Advantages

This circuit breaker offers exceptional reliability and performance consistency under standard operating conditions. Its Type C tripping characteristic makes it particularly suitable for circuits with moderate inrush currents, such as those powering lighting systems or small motors. The 10 kA breaking capacity ensures that the device can safely interrupt high fault currents, providing an essential layer of protection for connected appliances and wiring. Its compact design allows for efficient use of space within distribution boards, while the high-quality materials used in its manufacturing ensure a long service life and stable operation.

Suitable for

Residential electrical distribution boards
Commercial office power systems
Protection of lighting circuits
Small motor and appliance power lines

When it may not be suitable

This device is not intended for use in environments with high levels of moisture, dust, or corrosive gases, as it carries an IP20 rating. It is also not suitable for circuits requiring a different tripping curve, such as Type B for purely resistive loads or Type D for heavy inductive loads with high starting currents.

Number of poles: 1
Tripping characteristic: Type C
Breaking capacity: 10 kA
Operating voltage: 240-415 V
Frequency: 50-60 Hz
Protection rating: IP20

How to use

The Legrand TX3 circuit breaker is designed for mounting onto a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the power supply is completely disconnected before attempting any installation or maintenance work. The device is connected by securing the input and output wires into the designated terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

Ensure the 20 A rating matches the requirements of your specific circuit load.
Verify that the Type C characteristic is appropriate for the equipment connected to the circuit.
Check the available space in your distribution board to accommodate the 17.8 mm width.
Confirm that the installation environment meets the IP20 protection requirements.

Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test of the tripping mechanism periodically to ensure continued protection. Do not exceed the rated current capacity to avoid nuisance tripping or potential damage to the device.
