The LE-403551 miniature circuit breaker is a high-class solution from the renowned manufacturer Legrand, designed for professional electrical installations. The device features a three-phase design and a rated current of 63A, making it an ideal choice for protecting high-load circuits. A key feature of this model is the C-type tripping characteristic, which has been optimized for devices generating high inrush currents, such as electric motors or transformers. As a result, the user gains assurance that the system will not experience accidental disconnections during machine startup, while maintaining full protection against the effects of short circuits and overloads.

The product's advantages are numerous and primarily include reliability and durability resulting from the use of the highest quality insulating materials. The housing made of durable plastic ensures safe operation and resistance to mechanical damage. Installation of the device is extremely simple and fast thanks to the standard mounting on a TS-35 DIN rail, which allows for easy integration into most modern electrical switchboards. Additionally, the circuit breaker offers the possibility of expansion with DX3 series accessories, such as auxiliary contacts or releases, which significantly increases the functionality of the entire energy management system. Precise screw terminals guarantee a durable and stable connection of wires, minimizing the risk of contact overheating. By choosing a Legrand brand product, you are investing in the safety of the installation and the continuity of operation of connected devices, which is crucial both in the industrial sector and in demanding home installations.
