4. የአሠራር መመሪያዎች
The ABB S203-B16 circuit breaker is operated via a toggle actuator.
- ለማብራት፡- Push the toggle actuator upwards to the "ON" position.
- ለማጥፋት፡- Push the toggle actuator downwards to the "OFF" position.
- የጉዞ አመላካች፡ In case of an overcurrent or short circuit, the toggle actuator will automatically move to an intermediate "TRIPPED" position.
- ከጉዞ በኋላ ዳግም ማስጀመር; 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. ጥገና
The ABB S203-B16 circuit breaker requires minimal maintenance. Regular inspections are recommended to ensure proper function and safety.
