Product information

Description

The Legrand TX3 miniature circuit breaker is a high-quality electrical protection device designed to safeguard circuits against overloads and short circuits. Engineered for reliability, this 1-pole breaker is suitable for residential and commercial electrical systems operating between 240V and 415V. With a 16A rated current and a Type D tripping characteristic, it is specifically designed to handle high inrush currents, making it an essential component for maintaining electrical safety and system integrity.

Advantages

This circuit breaker offers robust performance through its 6kA breaking capacity, ensuring effective protection during fault conditions. The compact design allows for efficient use of space within distribution boards, while the high-quality construction from Legrand guarantees long-term durability and consistent operation. Its Type D characteristic provides the necessary flexibility for circuits with inductive loads, preventing nuisance tripping during startup.

Suitable for

Residential electrical distribution boards
Commercial building power systems
Circuits with high inrush current equipment
Protection of lighting and small power circuits

When it may not be suitable

This device is not intended for use in environments where the ambient conditions exceed the IP20 protection rating, such as areas with high moisture, dust, or direct exposure to the elements. It is also not suitable for applications requiring a different tripping curve, such as sensitive electronic equipment that may require Type B or C characteristics.

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the power supply is disconnected before installation. The device is mounted by snapping it onto the rail, and electrical connections are made via the integrated terminals. Once installed, the breaker can be manually switched on or off using the front toggle, and it will automatically trip to the off position in the event of an electrical fault.

What to consider before purchase

Verify that the 16A rating matches your circuit requirements
Ensure the Type D characteristic is appropriate for your specific load type
Check that the installation space accommodates the 17.8mm width
Confirm compatibility with your existing distribution board system
