Product Positioning
The Siemens SENTRON 5SY6404-7 is a 4-pole miniature circuit breaker with a C-characteristic curve, a rated current of 4A, and provides stable overload and short-circuit protection.
Core Product Advantages and Features
C-type bounce characteristics
The instantaneous trip current is 5 to 10 times the rated current, making it suitable for general lighting, socket circuits, and load protection with moderate surge current.
Precise classification of rated current
It offers a 4A rated current specification, which can be accurately selected according to the actual circuit load to avoid circuit breaker capacity mismatch.
4-pole structure design
The four poles can simultaneously disconnect the corresponding number of phase conductors, improving the safety of power distribution system maintenance and repair.
Standardized installation dimensions
The installation depth is 70mm, which conforms to the standard DIN rail installation specifications, making it convenient for the design of the distribution box and on-site replacement construction.
