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

4A rated current

Branch circuit protection suitable for small control boxes and indicator light circuits

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.
