How it works and how to install it
The circuit breaker is mounted on a 35mm DIN rail in the electrical panel, between the power source and the consumers. Upon detecting an overload or short circuit, the tripping mechanism automatically interrupts the circuit, protecting connected equipment. Installation requires knowledge of electricity and compliance with safety regulations — intervention by an authorized electrician is recommended.
Frequently asked questions
