How to use

Install the circuit breaker in the distribution board following the electrical code requirements and the manufacturer's mounting recommendations for DIN-rail devices. Before installation, switch off the main supply and verify absence of voltage. Connect the incoming and outgoing conductors to the appropriate terminals, ensuring tight and secure connections. After mounting, restore power and test the breaker by switching it on and off and by performing routine functional tests to confirm correct tripping behavior under simulated load conditions.

Recommendations

Ensure selection of the correct rated current and characteristic curve for the protected circuit; verify compatibility with the panel's busbar and terminal capacity. Periodically inspect the breaker and connections for signs of wear, overheating, or corrosion, and replace the device if any abnormal behavior or damage is observed. All installation and maintenance should be carried out by a qualified electrician in accordance with local regulations and safety standards.
