The circuit breaker is a device designed to protect circuits with moderate inductive loads, such as motors or large equipment
It has an interrupting capacity of 15KA, which is ideal for circuits with inductive loads due to the tripping curve C, which is triggered 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.
