5. Операция
The QOB120CP circuit breaker operates automatically to protect circuits from overcurrent conditions.
- Положение ВКЛ: When the circuit breaker handle is in the "ON" position, power is supplied to the circuit.
- Положение ВЫКЛ: 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.
Сброс сработавшего выключателя:
- Выявите причину: Before resetting, attempt to identify and correct the cause of the trip (e.g., unplug overloaded appliances).
- Полный ВЫКЛ. Firmly push the circuit breaker handle all the way to the "OFF" position. This resets the internal tripping mechanism.
- Включать: 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. Техническое обслуживание
The Square D QOB120CP circuit breaker is designed for reliable, long-term operation and requires minimal maintenance.
- Регулярный осмотр: 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.
- Уборка: 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.
