The MTV1-12/630-31.5KA vacuum circuit breaker operates on a sophisticated principle to ensure electrical safety. When an overload or short-circuit is detected, the current sensor relays signals to the intelligent controller. This controller then activates the tripping coil, which releases the energy-stored spring in the operating mechanism. This action causes the contacts to separate rapidly, effectively extinguishing the arc and preventing damage.

Key internal components include a robust operating mechanism for precise control, fixed terminals for secure connections, a vacuum interrupter as the core arc-extinguishing element, and a drawout-type contact arm for flexibility. Silver-plated copper contacts enhance conductivity and resist oxidation, while the insulating cylinder and aviation connector ensure reliability and protection. The finger cluster contacts provide a stable electrical connection, and the drawout chassis supports smooth operation of movable parts.

This product is designed for high-performance applications in various sectors, offering tailored solutions through OEM and ODM services. It integrates advanced manufacturing and engineering to meet global standards, with certifications including CE and RoHS.
