The Siemens circuit breaker, is a 4-pole protective device that supports a rated current of 25A. It has an interrupting capacity of 10KA, which is ideal for circuits with inductive loads due to its tripping curve C, which trips when the current exceeds 5 to 10 times the rated current.
The C trip curve of a circuit breaker is designed to protect circuits that handle inductive loads, such as motors, transformers or equipment with high inrush currents.
This curve is triggered when the current exceeds 5 to 10 times the rated value, allowing the system to tolerate temporary current spikes without tripping the device unnecessarily.
It is ideal for industrial and commercial installations, where temporary overload is common at the startup of energy-intensive devices.
