2. Sikkerhedsoplysninger
Always adhere to local electrical codes and regulations during installation and operation. Installation should only be performed by qualified personnel.
- Sørg for, at strømmen er afbrudt før installation eller vedligeholdelse.
- Betjen ikke afbryderen, hvis den ser ud til at være beskadiget.
- Brug passende personlige værnemidler (PPE).
- Refer to the wiring diagrams for correct connections.
3. Opsætning og installation
The S203-B16 circuit breaker is designed for DIN-rail mounting.
- Montering: Securely attach the circuit breaker to a standard DIN-rail. Ensure the mounting clip engages properly.
- Ledningsføring: Connect the electrical conductors to the screw terminals. The wire size supported is 18 - 4 AWG for conductors and 18 - 8 AWG for busbars.
- Terminalstramning: Sørg for, at alle skrueterminaler er spændt til det angivne moment for at forhindre løse forbindelser og overophedning.

4. Betjeningsvejledning
The ABB S203-B16 circuit breaker is operated via a toggle actuator.
- At tænde: Push the toggle actuator upwards to the "ON" position.
- At slukke: Push the toggle actuator downwards to the "OFF" position.
- Tripindikation: 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. Vedligeholdelse
The ABB S203-B16 circuit breaker requires minimal maintenance. Regular inspections are recommended to ensure proper function and safety.
- Visuel inspektion: Undersøg regelmæssigt afbryderen for tegn på fysisk skade, misfarvning eller løse forbindelser.
- Rensning: If necessary, clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Terminaltjek: Verify that all terminal connections remain tight.
- Miljøforhold: Ensure the operating environment remains within the specified temperature range (-25 to 55 deg C) and IP20 enclosure rating.
6. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Afbryderen udløses ofte. | Overload, short circuit, or faulty appliance/wiring. | Reduce load, check for short circuits, inspect connected equipment and wiring. |
| Afbryderen nulstilles ikke. | 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. |
| Afbryderen føles varm. | Overbelastning, løse forbindelser eller intern fejl. | 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.
