Legrand TX3 P302 Residual Current Circuit Breaker 2P 25A 0.1A Type AC

The Legrand TX3 P302 is a high-quality 2-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in residential and commercial environments. This device is designed to detect and interrupt electrical circuits when earth leakage currents are identified, effectively protecting users and equipment from the risks associated with ground faults. With a rated current of 25A and a sensitivity of 0.1A, it serves as a critical component in modern electrical distribution boards.

Advantages

This RCCB offers robust protection by monitoring the balance of current between phase and neutral conductors. Its Type AC classification ensures reliable operation in standard electrical systems where leakage currents are sinusoidal. The Legrand TX3 series is recognized for its durability and ease of installation, making it a preferred choice for electricians and homeowners looking to enhance the safety profile of their electrical installations. The compact design allows for efficient use of space within consumer units.

Suitable for

• Residential electrical distribution boards
• Commercial office building circuits
• Protection of lighting and general-purpose socket circuits
• Preventing electrical shock hazards in standard AC installations

This device is not suitable for circuits where DC components are present, as it is specifically designed as a Type AC breaker. It should not be used as a primary protection device against short circuits or overloads, as it does not include integrated overcurrent protection functionality.

Key specifications

• Number of poles: 2
• Rated current: 25A
• Sensitivity: 0.1A
• Type: AC
• Mounting: DIN rail

The Legrand TX3 P302 is installed by a qualified professional into a standard DIN rail distribution board. It should be connected in series with the circuit it is intended to protect, ensuring that both the phase and neutral wires pass through the device. Regular testing is required to verify the mechanical integrity of the tripping mechanism.

What to consider before purchase

• Verify that the rated current matches your circuit requirements
• Ensure the sensitivity level is appropriate for your specific safety application
• Confirm compatibility with your existing distribution board layout
• Check local electrical regulations regarding the use of Type AC devices

Regularly test the residual current circuit breaker using the integrated test button at least every six months to ensure the device remains in optimal working condition and provides reliable protection.
