## Long description

The Legrand TX3 403751 is a high-quality 3-pole miniature circuit breaker engineered to provide robust electrical protection in demanding environments. With a rated current of 6A and a 6kA breaking capacity, this device is specifically designed to safeguard electrical circuits against overloads and short circuits. It operates efficiently within a voltage range of 240-415V at 50-60Hz, making it a versatile component for modern electrical distribution systems.
Advantages
This circuit breaker offers exceptional reliability due to its Type D tripping characteristic, which is ideal for circuits with high inrush currents, such as those powering motors or transformers. The compact design allows for seamless integration into standard distribution boards, saving valuable space while ensuring a clean and organized installation. Its durable construction ensures long-term performance and consistent protection for sensitive electrical equipment.
Suitable for
Industrial machinery and motor control circuits
Commercial electrical distribution boards
Systems with high inductive loads
Protection of lighting circuits with high starting currents
When it may not be suitable
This device is not intended for residential applications where standard Type B or Type C tripping characteristics are typically required for general household appliances. Using a Type D breaker in circuits without significant inrush currents may result in delayed protection during a fault.
