How to use

Install the circuit breaker into the distribution board following local electrical codes and the panel manufacturer’s instructions. Ensure power is disconnected before fitting the device. Connect the supply and load conductors to the designated terminals, verify tight and secure connections, and restore power to test correct operation. After installation, verify that the breaker trips under test conditions appropriate for the circuit and that there are no abnormal noises or heating during normal operation.

Recommendations

Specify the breaker rating and characteristics required for the protected circuit prior to installation, and use a qualified electrician to perform mounting and connection. Periodically inspect connections and the device for signs of wear, corrosion or overheating, and replace the breaker if tripping becomes irregular or if physical damage is observed.
