4. Arahan Operasi
The HLD3600F circuit breaker features a toggle handle for manual operation and an internal thermal-magnetic trip unit for automatic protection.
4.1 Menghidupkan/Mematikan
- Untuk Menghidupkan: Push the toggle handle firmly to the 'ON' position.
- Untuk Mematikan: Push the toggle handle firmly to the 'OFF' position.
4.2 Trip Indication and Resetting
When an overcurrent or short circuit occurs, the breaker will automatically trip. The toggle handle will move to an intermediate 'TRIPPED' position (typically between ON and OFF).
- Kenalpasti Punca: Before resetting, investigate and resolve the cause of the trip (e.g., overloaded circuit, short circuit).
- Menetapkan semula: First, push the handle firmly to the 'OFF' position until it clicks. Then, push the handle firmly to the 'ON' position.
- If the breaker immediately trips again, do not attempt to reset it further. Consult a qualified electrician.
5. Penyelenggaraan
Penyelenggaraan tetap memastikan jangka hayat dan operasi yang boleh dipercayai bagi pemutus litar anda. Sentiasa putuskan sambungan kuasa sebelum melakukan sebarang penyelenggaraan.
