Figure 1: ABB ESB 20-20 230 Volt Contactor. This image displays a white and grey ABB ESB 20-20 contactor, highlighting the A1 and A2 coil terminals at the top and bottom, respectively, and the main power terminals labeled 1, 3, 2, and 4. The ABB logo and model number are clearly visible on the front face of the unit.
3. Turvallisuustiedot
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified and authorized personnel.
- Katkaise aina virta ennen kontaktorin asentamista, huoltoa tai irrottamista.
- Varmista, että kaikki johdotukset ovat paikallisten ja kansallisten sähkömääräysten mukaisia.
- Tarkista oikea voltage and current ratings before connecting the contactor to a circuit.
- Älä käytä kontaktoria, jos se näyttää vaurioituneelta.
4. Asennus ja asennus
The ABB ESB 20-20 contactor is designed for DIN rail mounting, facilitating easy integration into control panels.
- Asennus: Securely attach the contactor to a standard 35mm DIN rail. Ensure it clicks firmly into place.
- Virtajohdot: 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.
- Käämin johdotus: 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.
- Vahvistus: 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. Käyttöohjeet
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.
- Käämin virittäminen: Apply 230 Volts AC to terminals A1 and A2. The contactor will audibly click as the contacts close.
- Käämin jännitteettömyys: 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.
- Tilan ilmaisin: Joissakin malleissa voi olla visuaalinen ilmaisin, joka näyttää kontaktorin tilan (auki/kiinni).
6. Huolto
Regular maintenance ensures the longevity and reliable operation of your ABB ESB 20-20 contactor.
- Silmämääräinen tarkastus: Tarkista kontaktori säännöllisesti mahdollisten fyysisten vaurioiden, värinmuutosten tai löysien liitosten varalta.
- Puhdistus: Ensure the contactor is free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Do not use solvents.
- Yhteyden tarkistus: With power disconnected, verify that all terminal screws are tight. Loose connections can lead to overheating and failure.
7. Vianmääritys
Jos kontaktori ei toimi odotetulla tavalla, suorita seuraavat perustarkastukset:
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Contactor does not energize (no click) | Ei ohjausta voltage to A1/A2; incorrect voltage; open coil circuit. | Check control circuit power supply; verify 230V at A1/A2; test coil continuity. |
| Kontaktori vetää, mutta kuorma ei saa virtaa | 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. |
| Kontaktori ylikuumenee | Overcurrent; loose connections; incorrect voltage. | Verify load current is within 20A rating; tighten all connections; confirm 230V coil voltage. |
