How it works and how to install it
The circuit breaker constantly monitors the electrical current and trips automatically when it detects an overload or short circuit, cutting off power to protect the installation. Mounting is done on an electrical panel or DIN rail by screw fixing in the dedicated holes. You connect the wires to the upper and lower three-phase terminals, respecting the electrical diagram of the installation. It does not require fuses or special maintenance — upon tripping, you simply reactivate the circuit breaker after troubleshooting the problem.
Frequently Asked Questions
