## Long description

The Legrand TX3 3-pole miniature circuit breaker is a robust electrical protection device engineered to ensure safety and reliability in demanding power distribution systems. With a rated current of 50 A and compatibility with voltages ranging from 240 V to 415 V, this circuit breaker is designed to handle significant electrical loads while maintaining consistent performance across standard 50-60 Hz frequencies.
Advantages
This device offers superior protection for electrical circuits by effectively managing high inrush currents, which are common in industrial and commercial environments. Its Type D tripping characteristic provides a delayed response to short-circuit currents, preventing nuisance tripping during the startup of heavy machinery or inductive loads. The compact 3-pole design allows for efficient space utilization within electrical distribution boards, while the high-quality construction ensures long-term operational stability and safety.
Suitable for
Industrial machinery and motor control centers
Commercial electrical distribution boards
Systems with high inrush current requirements
Three-phase electrical installations
This circuit breaker may not be suitable for residential lighting circuits or standard household appliances where a Type B or Type C characteristic is typically required to ensure faster tripping during minor faults. It is also not intended for use in environments exposed to moisture or dust without an appropriate protective enclosure, as the device itself is rated IP20.
