- Verify all connections are secure and properly torqued according to specifications.
- Ensure the circuit breaker's ratings match the system requirements.
3. Persediaan dan Pemasangan
The GE SELA36AT0150 is a bolt-on mount circuit breaker. Proper installation is crucial for safe and reliable operation.
3.1 Pemeriksaan Pra-Pemasangan
- Confirm the circuit breaker's voltage, current, and interrupting ratings are compatible with the electrical system.
- Inspect the circuit breaker for any physical damage. Do not install damaged units.
- Pastikan permukaan pelekap bersih, kering dan kukuh dari segi struktur.
3.2 Arahan Pemasangan
- De-energize the electrical panel or system where the breaker will be installed. Verify zero voltage dengan multimeter.
- Position the circuit breaker in the designated slot or mounting location.
- Secure the breaker using appropriate bolts and hardware for bolt-on mounting. Ensure it is firmly seated.
- Connect the load and line conductors to the appropriate terminals. The breaker includes a set of bottom lugs.
- Refer to the product label for specific wire ranges and torque specifications:
- Wire Range: #12 - 3/0 CU, #12 - 3/0 AL
- Torque: #12-#10: 35 lb-in, #8-#3: 100 lb-in, #2-3/0: 150 lb-in
- Periksa semula semua sambungan untuk memastikan ketat dan penebat yang betul.

4. Arahan Operasi
The GE SELA36AT0150 circuit breaker is designed for simple operation, primarily acting as an ON/OFF switch and an automatic protective device.
4.1 Menghidupkan/Mematikan
- Untuk memutar litar ON, firmly push the handle to the "ON" position.
- Untuk memutar litar DIMATIKAN, firmly push the handle to the "OFF" position.
4.2 Tripping and Resetting
If an overcurrent or short circuit condition occurs, the breaker will automatically "trip" to the center position (between ON and OFF) to protect the circuit. To reset a tripped breaker:
- First, move the handle completely to the "OFF" position. This resets the internal mechanism.
- Investigate and resolve the cause of the trip (e.g., overloaded circuit, short circuit).
- Once the issue is resolved, firmly push the handle to the "ON" position to restore power.
- If the breaker immediately trips again, do not attempt to reset it repeatedly. Consult a qualified electrician.
5. Penyelenggaraan
Pemutus litar biasanya memerlukan penyelenggaraan yang minimum. Walau bagaimanapun, pemeriksaan berkala disyorkan untuk memastikan operasi selamat berterusan.
- Pemeriksaan Visual: Annually inspect the breaker for signs of physical damage, discoloration, or loose connections.
- Pembersihan: Keep the area around the breaker clean and free of dust and debris. Use a dry, non-conductive cloth for cleaning. Do not use liquids.
- Pemeriksaan Sambungan: Periodically (e.g., every 3-5 years, or as per local codes) have a qualified electrician check the tightness of terminal connections.
- Ujian: For critical applications, periodic testing of the breaker's trip mechanism by a qualified professional may be required.
Nota: Do not attempt to open or repair the circuit breaker. There are no user-serviceable parts inside.
6. Penyelesaian masalah
Bahagian ini menangani isu biasa yang mungkin anda hadapi dengan pemutus litar anda.
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Perjalanan pemutus kerap. | Litar terlebih beban, litar pintas, kerosakan pembumian atau perkakas yang rosak. | Kurangkan beban pada litar. Cabut plag peralatan. Periksa pendawaian untuk kerosakan. Jika masalah berterusan, rujuk juruelektrik yang berkelayakan. |
| Pemutus tidak akan ditetapkan semula. | Persistent fault (short circuit/overload) or internal breaker damage. | Ensure the handle is pushed fully to "OFF" before attempting to reset. If it still won't reset, do not force it. Call a qualified electrician. |
| Tiada kuasa ke litar, tetapi pemutus litar ON. | Loose connection, wiring issue, or internal breaker failure. | This indicates a serious issue. Immediately turn off the breaker and consult a qualified electrician. Do not attempt to diagnose or fix yourself. |
For any issues not covered here, or if troubleshooting steps do not resolve the problem, always contact a qualified and licensed electrician.
