## Long description

The Legrand TX3 4-pole miniature circuit breaker is a robust electrical protection device engineered to safeguard circuits against overloads and short circuits. Designed for integration into residential and commercial distribution boards, this 20A breaker ensures consistent performance and safety in electrical installations operating between 240V and 415V. Its compact design and reliable tripping mechanism make it a standard choice for modern electrical infrastructure.
Advantages
This circuit breaker offers high operational reliability due to its precise Type B tripping characteristic, which is specifically calibrated to respond quickly to fault conditions. The 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral wire, providing comprehensive protection for three-phase systems. Its construction meets rigorous quality standards, ensuring durability and long-term stability within electrical panels. The device is easy to install and integrates seamlessly with standard distribution board layouts.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Three-phase electrical circuits
Protection of lighting and general-purpose socket outlets
This device may not be suitable for circuits with high inrush currents, such as those powering large motors or heavy industrial machinery, where a Type C or Type D tripping characteristic would be required to prevent nuisance tripping. It is also intended for indoor use only and should not be installed in environments exposed to moisture, dust, or extreme temperatures without appropriate protective enclosures.
