5. Funtzionamendua
The QOB120CP circuit breaker operates automatically to protect circuits from overcurrent conditions.
- ON posizioa: When the circuit breaker handle is in the "ON" position, power is supplied to the circuit.
- OFF posizioa: Moving the handle to the "OFF" position manually disconnects power to the circuit.
- Tripped Position (Visi-Trip): If an overload or short-circuit occurs, the circuit breaker will automatically trip. The handle will move to a midpoint position between "OFF" and "ON," and a highly visible red indicator will appear, making it easy to identify the tripped breaker.
Jauzi egin duen etengailu bat berrezartzea:
- Identifikatu kausa: Before resetting, attempt to identify and correct the cause of the trip (e.g., unplug overloaded appliances).
- Guztiz itzalita: Firmly push the circuit breaker handle all the way to the "OFF" position. This resets the internal tripping mechanism.
- Aktibatu: Push the handle firmly to the "ON" position. If the breaker immediately trips again, do not attempt to reset it further. Contact a qualified electrician.
6. Mantentzea
The Square D QOB120CP circuit breaker is designed for reliable, long-term operation and requires minimal maintenance.
- Ohiko ikuskapena: Periodically inspect the circuit breaker and electrical panel for any signs of damage, discoloration, or loose connections. This should be done by a qualified electrician.
- Garbiketa: Keep the area around the electrical panel and circuit breakers clean and free from dust and debris. Do not use liquids for cleaning inside the panel.
- Erabiltzaileak ez du zerbitzurik gabeko piezarik: This device contains no user-serviceable parts. Do not attempt to disassemble or repair the circuit breaker.
