5SY5101-7
The Siemens SENTRON 5SY5101-7 AC/DC miniature circuit breaker is a single-pole, C-curve circuit breaker with a rated current of 1A. It can be used in 230/400V AC and 220V DC circuits, with a breaking capacity of 10kA. It is suitable for PLC and instrument power supplies, sensors and control circuits, as well as DC control power supply protection.
Product Positioning
The 5SY5101-7 is a Siemens SENTRON 5SY5 series AC/DC dual-use (UC) miniature circuit breaker. It is a single-pole, C-curve circuit breaker with a rated current of 1A. The same circuit breaker can be used for 230/400V AC and 220V DC circuits, and is suitable for control panels and DC control power supply protection that use both AC and DC.
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.
Single-pole compact design
With a single module width of 18mm, it is suitable for overload and short circuit protection of single-phase branch circuits and can be arranged in high density in the distribution box.
AC/DC dual-use
The same model can be used for 230/400V AC and 220V DC circuits, and the spare parts specifications can be standardized for control panels that can be used for both AC and DC.
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.
