Product information

Description

The Legrand TX3 Miniature Circuit Breaker is a high-quality electrical protection device designed to safeguard residential and industrial circuits from overloads and short circuits. This 1-pole unit is engineered for precision and reliability, ensuring that electrical distribution systems remain stable under varying load conditions. With a rated current of 20 A and a robust Type D tripping characteristic, it is specifically built to handle high inrush currents, making it an essential component for modern electrical installations.

Advantages

The primary advantage of this circuit breaker is its specialized Type D tripping curve, which allows it to manage significant current surges without nuisance tripping, a common issue with standard breakers when starting inductive loads. Its compact design ensures efficient use of space within distribution boards, while the high-quality construction from Legrand guarantees long-term durability and consistent performance. The device is easy to install and provides a reliable safety barrier that helps prevent damage to wiring and connected equipment during electrical faults.

Suitable for

Industrial machinery with high starting currents
Large motor applications
Residential distribution boards
Lighting circuits with high inrush requirements

When it may not be suitable

This circuit breaker is not intended for use in circuits where standard Type B or Type C tripping characteristics are required, as the Type D curve is specifically designed for high-surge applications. Using it in inappropriate circuits may result in a failure to trip quickly enough during a fault, potentially compromising safety.

Key specifications

Rated current: 20 A
Tripping characteristic: Type D
Number of poles: 1
Voltage rating: 240-415 V
Frequency: 50-60 Hz
Protection rating: IP20
Dimensions: 17.8 mm x 77.8 mm x 88 mm

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within an electrical distribution enclosure. Ensure that the power supply is disconnected before beginning the installation. The device is mounted by snapping it onto the rail and securing the wire connections firmly to the terminals, ensuring that the cable cross-section is appropriate for a 20 A load. Once installed, the breaker can be switched on to provide power to the circuit.

What to consider before purchase

Verify that the Type D characteristic is appropriate for your specific load requirements.
Ensure the 20 A rating matches the capacity of your wiring and connected devices.
Check the available space in your distribution board for a 1-pole module.
Confirm that the operating voltage and frequency match your local electrical grid.

Usage recommendations: Regularly inspect the circuit breaker for signs of wear or heat damage. It is recommended to test the functionality of the breaker periodically to ensure it remains in optimal working condition.
