Product Positioning

The SENTRON 5SY6663-7 is a Siemens 5SY6 series 3P+N (three-phase plus neutral) four-pole miniature circuit breaker with C-type tripping characteristics and a short-circuit breaking capacity of 6kA. It is suitable for circuit protection in three-phase four-wire power distribution systems.

Core Product Advantages and Features
63A high current rating
Suitable for large three-phase power circuits, meeting the protection requirements for high load currents.
3P+N quadrupole simultaneous motion
The three phases and neutral electrode are interconnected and trip; in case of a fault, all polarities are simultaneously disconnected to ensure safety.
C-type bounce characteristics
Instantaneous trip ratio of 5~10In, suitable for three-phase loads with starting surge current, including motors and other components.
Standard DIN rail mounting
Standard 35mm DIN rail mounting, four-pole integrated design saves internal space in the distribution box.
