Connection capacity: accepts conductors up to 50 mm²
Functional protection: designed for overcurrent and short-circuit interruption
Application: suitable for residential and light commercial circuits
How to use
Install the breaker onto a compatible DIN-rail inside the distribution board and secure it according to standard electrical installation procedures. Connect the line conductor to the breaker input and the load conductor to the output, ensuring conductors are sized appropriately for the circuit and tightened to the manufacturer-recommended torque. Verify correct orientation and clearances, then restore power and test the circuit to confirm the breaker trips under simulated fault conditions if required. All work must be carried out by a qualified electrician following local regulations and safety standards.
Usage recommendations
Select the breaker rating and tripping curve that match the circuit load and coordination requirements. Periodically inspect terminals for secure connections and signs of overheating. For installations with high fault currents or specific selective protection needs, coordinate with upstream and downstream devices to achieve proper discrimination.
