2. Коопсуздук маалыматы
Always adhere to local electrical codes and regulations during installation and operation. Installation should only be performed by qualified personnel.
- Орнотуудан же тейлөөдөн мурун электр энергиясы өчүрүлгөнүн текшериңиз.
- Эгерде өчүргүч бузулуп калса, иштетпеңиз.
- Тиешелүү жеке коргонуу шаймандарын (ЖКК) кийиңиз.
- Refer to the wiring diagrams for correct connections.
3. Орнотуу жана орнотуу
The S203-B16 circuit breaker is designed for DIN-rail mounting.
- Монтаждоо: Securely attach the circuit breaker to a standard DIN-rail. Ensure the mounting clip engages properly.
- Зымдар: Connect the electrical conductors to the screw terminals. The wire size supported is 18 - 4 AWG for conductors and 18 - 8 AWG for busbars.
- Терминалды бекемдөө: Ensure all screw terminals are tightened to the specified torque to prevent loose connections and overheating.

4. Иштөө нускамалары
The ABB S203-B16 circuit breaker is operated via a toggle actuator.
- Күйгүзүү: Push the toggle actuator upwards to the "ON" position.
- Өчүрүү: Push the toggle actuator downwards to the "OFF" position.
- Сапардын көрсөткүчү: In case of an overcurrent or short circuit, the toggle actuator will automatically move to an intermediate "TRIPPED" position.
- Resetting After Trip: To reset the circuit breaker after a trip, first move the toggle completely to the "OFF" position, then push it upwards to the "ON" position. Investigate the cause of the trip before resetting.
5. Техникалык тейлөө
The ABB S203-B16 circuit breaker requires minimal maintenance. Regular inspections are recommended to ensure proper function and safety.
- Визуалдык текшерүү: Мезгил-мезгили менен автоматтык өчүргүчтө физикалык бузулуунун, түсүнүн өзгөрүшүнүн же туташтыруунун боштугунун белгилерин текшерип туруңуз.
- Тазалоо: If necessary, clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Терминал текшерүү: Verify that all terminal connections remain tight.
- Экологиялык шарттар: Ensure the operating environment remains within the specified temperature range (-25 to 55 deg C) and IP20 enclosure rating.
6. Кыйынчылыктарды
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Автоматтык өчүргүч тез-тез иштен чыгат. | Overload, short circuit, or faulty appliance/wiring. | Reduce load, check for short circuits, inspect connected equipment and wiring. |
| Автоматтык өчүргүч баштапкы абалга келтирилбейт. | Persistent fault, internal damage. | Ensure the fault is cleared. If it still doesn't reset, the unit may be damaged and require replacement. Consult a qualified electrician. |
| Автоматтык өчүргүч ысык сезилип жатат. | Ашыкча жүктөө, бош байланыштар же ички ката. | Reduce load, check terminal tightness, or replace the unit if overheating persists without apparent cause. |
If troubleshooting steps do not resolve the issue, contact a qualified electrician or ABB customer support.
