Siemens SENTRON 5SJ4115-8HG40 1.6A D-curve miniature circuit breaker

Product Positioning

The 5SJ4115-8HG40 is a D-curve miniature circuit breaker with a rated current of only 1.6A. It adopts an equal polarity terminal design and is suitable for overload and short-circuit protection of low-current control circuits.

Core Product Advantages and Features

D-type instantaneous break-out characteristics

With a D-curve design, the instantaneous trip current is approximately 10 to 14 times the rated value, and the tripping time is later than that of the C-curve, making it suitable for small loads with startup surges.

Low rated current specifications

With a rated current of only 1.6A, it is one of the smallest specifications in this series, making it suitable for small load protection such as instrumentation and control circuits.

Same polarity terminal design

It adopts equal polarity terminal configuration, which facilitates the parallel wiring of multiple circuits to DIN rail.

Compact installation size

With a module pitch of 18mm and an installation depth of 70mm, it meets UL489 standards and saves space in the distribution box.
