5SP3863-2 SIEMENS

The 5SP3863-2 is a Siemens main miniature circuit breaker (MCB), also known as a SHU (Schutzschalter). This device provides reliable overcurrent and short-circuit protection for electrical circuits in residential, commercial, and industrial applications. It features a 3x 1-pole configuration, effectively providing three independent single-pole breakers within a single unit. Each pole is rated for a current of 63A, making it suitable for circuits with higher power demands. The breaker is designed for a voltage rating of 230/400V AC. Its primary function is to interrupt the flow of electricity in the event of an overload or short circuit, preventing damage to equipment and reducing the risk of electrical fires. The 5SP3863-2 is specifically designed for mounting on 40mm busbars, ensuring a secure and standardized installation within electrical panels. This mounting configuration simplifies installation and maintenance procedures. Siemens MCBs are known for their quality, reliability, and compliance with international safety standards, providing peace of mind for electrical installations.
