The circuit breaker is an ideal protective device for residential and commercial electrical systems. Designed to automatically interrupt current flow in the event of an overload or short circuit.
The trip curve B of a circuit breaker is designed to intervene quickly in the event of an overload or short circuit, protecting circuits with normal loads, such as those found in residential or commercial installations. Here are the main features:
- Magnetic trip: Triggers when the current exceeds 3 to 5 times the rated current
- Common use: Circuits with resistive loads, such as lights or small appliances
- Fast tripping time: Ideal for protection of electronic devices sensitive to overcurrents
