Product Positioning
The 5SY4650-7 is a Siemens SENTRON 5SY4 series 3P+N miniature circuit breaker. It adopts a C-type tripping curve, has a rated current of 50A, a breaking capacity of 10kA, and an installation depth of 70mm. It is suitable for use in distribution panel feeders and main circuits of large power equipment.
Core Product Advantages and Features
C-type tripping curve
The instantaneous tripping current is approximately 5 to 10 times the rated current, which can withstand the inrush current of inductive loads such as motors and transformers, reducing false tripping.
3P+N four-line synchronous opening and closing
When all three phases plus the neutral line are disconnected simultaneously, the three-phase four-wire circuit can be completely isolated, making it suitable for three-phase power distribution with single-phase loads.
10kA interruption capacity
Rated short-circuit breaking capacity of 10kA according to IEC/EN 60898-1, suitable for power distribution in industrial and commercial buildings.
DIN rail quick installation
Standard 35mm DIN rail snap-fit installation; inlet and outlet terminals can be used with busbars, making installation and replacement convenient.
