Siemens SENTRON 5SY7105-7 Single-pole Type C Miniature Circuit Breaker 0.5A 15kA MCB

Product Positioning

The SENTRON 5SY7105-7 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 the end circuits in power distribution systems.

Core Product Advantages and Features

0.5A minimum rated current

Specifically designed for micro-ampere level circuits in instrumentation and signal processing, providing more delicate protection.

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.
