The ABB logo and model number are clearly visible on the front face of the unit.
3. Sigurnosne informacije
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified and authorized personnel.
- Uvijek isključite napajanje prije instaliranja, servisiranja ili uklanjanja kontaktora.
- Osigurajte da sve instalacije budu u skladu s lokalnim i nacionalnim električnim propisima.
- Potvrdite tačan voltage and current ratings before connecting the contactor to a circuit.
- Ne koristite kontaktor ako izgleda oštećeno.
4. Postavljanje i instalacija
The ABB ESB 20-20 contactor is designed for DIN rail mounting, facilitating easy integration into control panels.
- Montaža: Securely attach the contactor to a standard 35mm DIN rail. Ensure it clicks firmly into place.
- Električno ožičenje: Connect the main power circuit to terminals 1 and 3 (input) and terminals 2 and 4 (output). Ensure proper wire gauge for the 20A rating.
- Ožičenje zavojnice: Connect the 230 Volt control voltage to the coil terminals A1 and A2. Observe correct polarity if applicable, though AC coils are typically non-polar.
- Potvrda: Double-check all connections for tightness and correct wiring according to your circuit diagram.
Refer to your specific application's wiring diagram for detailed connection instructions.
5. Uputstvo za upotrebu
The ESB 20-20 contactor operates by energizing its coil, which then closes the main power contacts, allowing current to flow through the connected load.
- Napajanje zavojnice: Apply 230 Volts AC to terminals A1 and A2. The contactor will audibly click as the contacts close.
- Isključivanje zavojnice iz struje: Remove the 230 Volt AC supply from terminals A1 and A2. The contactor will audibly click as the contacts open, interrupting the power to the load.
- Indikator statusa: Neki modeli mogu uključivati vizualni indikator koji prikazuje stanje kontaktora (otvoreno/zatvoreno).
6. Održavanje
Regular maintenance ensures the longevity and reliable operation of your ABB ESB 20-20 contactor.
- Vizuelni pregled: Povremeno provjeravajte kontaktor na bilo kakve znakove fizičkog oštećenja, promjene boje ili labavih spojeva.
- čišćenje: Ensure the contactor is free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Do not use solvents.
- Provjera veze: With power disconnected, verify that all terminal screws are tight. Loose connections can lead to overheating and failure.
7. Otkrivanje problema
If the contactor is not functioning as expected, perform the following basic checks:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Kontaktor se ne uključuje (nema klika) | Bez kontrole voltage to A1/A2; incorrect voltage; open coil circuit. | Check control circuit power supply; verify 230V at A1/A2; test coil continuity. |
| Kontaktor se uključuje, ali opterećenje ne prima napajanje | Main power not connected; main contacts damaged; load circuit fault. | Check main power supply to terminals 1/3; inspect contacts for damage; check load wiring. |
| Kontaktor se pregrijava | Overcurrent; loose connections; incorrect voltage. | Verify load current is within 20A rating; tighten all connections; confirm 230V coil voltage. |
