Legrand TX3 Residual Current Circuit Breaker 16A 2P 10mA Type A

The Legrand TX3 residual current circuit breaker is a high-quality 2-pole electrical protection device engineered to safeguard residential and commercial circuits. With a rated current of 16A and a high sensitivity of 10mA, this Type A device is specifically designed to detect both AC and pulsating DC residual currents, ensuring comprehensive protection against electrical faults and potential hazards.

Advantages

This circuit breaker offers superior reliability and safety for modern electrical installations. Its Type A classification makes it highly versatile, as it can detect leakage currents in circuits containing electronic components, such as those found in modern household appliances or lighting systems. The compact modular design allows for easy integration into standard distribution boards, while the robust construction ensures long-term operational stability and effective fault detection.

Suitable for

• Residential electrical distribution boards
• Protection of circuits with sensitive electronic equipment
• Bathroom and kitchen installations requiring high sensitivity
• Commercial electrical systems with specific leakage protection needs

When it may not be suitable

This device is not intended for use in high-power industrial applications that exceed its 16A current rating. It is also not suitable for circuits requiring a different sensitivity level or those that do not require Type A protection, such as simple resistive loads where a standard Type AC breaker might suffice.

Key specifications

• Rated current: 16A
• Number of poles: 2
• Sensitivity: 10mA
• Type: A
• Mounting: DIN rail

How to use

The device should be installed by a qualified electrician in a standard distribution board on a DIN rail. Once installed, the circuit breaker operates automatically to monitor the electrical current. In the event of a leakage current exceeding the 10mA threshold, the device will trip and disconnect the power supply to the protected circuit. Users can manually reset the device using the toggle switch after the fault has been identified and resolved.

What to consider before purchase

• Ensure the 16A rating matches your circuit requirements
• Verify that the 10mA sensitivity is appropriate for the intended application
• Confirm that Type A protection is required for your specific equipment
• Check available space in your distribution board

Usage recommendations

Regularly test the functionality of the residual current circuit breaker by pressing the integrated test button at least every six months to ensure the mechanical tripping mechanism remains operational.
