How to use
Install the QOLTEC 52591 on a standard TH35 DIN rail inside the distribution board, ensuring the supply conductor is connected to the breaker input and the load conductor to the output. Verify the correct polarity and tighten terminal screws to the manufacturer's recommended torque. Use the breaker switch to manually connect and disconnect the circuit; in case of fault the device will trip automatically and can be reset after clearing the cause of the overload or short circuit. Ensure the installation is carried out by a qualified electrician and power is disconnected before wiring.
Usage recommendations
Choose the QOLTEC 52591 for single-phase circuits requiring 20 A protection with C-characteristic behaviour. Confirm that the rated current and trip characteristic match the protected load and coordination scheme of the distribution board. Regularly inspect terminals for tightness and signs of overheating and replace the breaker if mechanical damage or persistent tripping occurs.
