## Long description

The Legrand TX3 403734 is a high-quality 2-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in commercial and industrial environments. This device is specifically designed to safeguard installations against overloads and short circuits, ensuring consistent performance and safety. With its precise engineering, it effectively manages electrical flow within a voltage range of 240-415 V, making it a reliable component for modern electrical distribution systems.
Advantages
This circuit breaker offers exceptional reliability due to its Type D tripping characteristic, which is specifically suited for handling high inrush currents often found in inductive loads like motors or transformers. The compact design allows for efficient use of space within electrical panels, while the durable construction ensures a long service life under standard operating conditions. Its dual-pole configuration provides simultaneous disconnection of both live conductors, enhancing the overall safety profile of the electrical installation.
Suitable for
Industrial machinery and motor control circuits
Commercial lighting systems with high inrush currents
Electrical distribution boards in professional settings
Protection of equipment with inductive characteristics
When it may not be suitable
This device is not intended for residential applications where Type B or Type C tripping characteristics are typically required for standard household appliances. Using a Type D breaker in circuits with low inrush currents may result in delayed protection during a fault condition.
