Product description

The Siemens 5SY4116-5 is a single-pole miniature circuit breaker featuring a Type A tripping characteristic and a 16A rated current. It operates at 230/400V with a significant 10kA breaking capacity, providing reliable protection against overcurrents. The Type A curve is designed for very fast tripping at low overcurrents, making it suitable for specific electronic applications.

This circuit breaker is typically used for protecting highly sensitive electronic circuits or semiconductor devices where extremely rapid detection of even small overcurrents is critical. Its application is specialized, often found in areas like telecommunications equipment or sensitive measurement instrumentation.

Stanlo Automation, a veteran-owned business specializing in industrial surplus, offers the Siemens 5SY4116-5. We ensure the availability of hard-to-find parts to keep your critical systems operational.

Frequently asked questions

Why would a Type A tripping curve be chosen for a 16A breaker like the Siemens 5SY4116-5?

The Type A tripping characteristic of the Siemens 5SY4116-5 is designed for very sensitive applications, tripping at lower overcurrents than Type B or C. While it has a 16A rating, it is specifically for protecting semiconductor devices or electronic circuits where even small overloads can cause immediate damage and require extremely rapid disconnection.
