## Long description

The Legrand TX3 miniature circuit breaker is a professional-grade protective device engineered to safeguard electrical circuits in both residential and commercial environments. This single-pole unit is designed to provide reliable protection against short circuits and overloads, ensuring the integrity of your electrical distribution system. With a robust construction and high-quality components, it offers consistent performance for demanding electrical installations.
Advantages
This circuit breaker stands out due to its high breaking capacity of 6kA, which allows it to handle significant fault currents safely. The Type D tripping characteristic makes it particularly suitable for circuits with high inrush currents, such as those connected to motors, transformers, or large lighting banks. Its compact design allows for efficient use of space within distribution boards, while the standardized mounting ensures compatibility with most modern electrical enclosures.
Suitable for
Protecting circuits with high inrush currents
Industrial and commercial electrical distribution systems
Residential installations requiring robust overload protection
Motor control circuits
When it may not be suitable
This device is not intended for use in environments where the ambient conditions exceed the IP20 rating, such as areas with high moisture, dust, or outdoor exposure without a protective enclosure. It is also not suitable for circuits requiring different tripping characteristics, such as Type B or C, which are more appropriate for standard household appliances or resistive loads.
