Product Positioning

The SENTRON 5SY7103-7 is a single-pole miniature circuit breaker from the Siemens 5SY7 series. It features a type-C tripping characteristic and a short-circuit breaking capacity of up to 15kA, making it suitable as an overload and short-circuit protection device for end circuits in power distribution systems.

Core Product Advantages and Features

3A rated current

Suitable for branch circuit protection of low-power control circuits and low-voltage systems

C-type bounce characteristics

Instantaneous trip rate of 5~10In, balancing inrush current protection during general load startup and fast short-circuit protection.

15kA high breaking capacity

With a rated short-circuit breaking capacity of 15kA, it complies with IEC 60898 standards, enhancing the system's protection level.

Standard DIN rail mounting

Using standard 35mm DIN rails for quick-release installation, requiring only one module in width, the distribution box layout saves more space.
