5. Operation
The TeSys Deca contactor is primarily used for on-off control of AC loads, such as motors. When the control circuit voltage (220 V AC 50/60 Hz) is applied to terminals A1 and A2, the main contacts (L1-T1, L2-T2, L3-T3) close, allowing power to flow to the connected load. When the control voltage is removed, the contacts open, disconnecting the load.
The contactor includes auxiliary contacts (1 NO + 1 NC) for signaling or interlocking purposes within a control system.
6. Maintenance
Regular inspection and maintenance are crucial for ensuring the longevity and reliable operation of your TeSys Deca contactor.
- Visual Inspection: Periodically check for any signs of physical damage, discoloration, loose connections, or excessive dust accumulation.
- Terminal Tightness: Re-tighten terminal screws to the specified torque values if necessary, especially after initial installation and during routine checks.
- Cleaning: Keep the contactor clean and free from dust and debris. Use a dry, lint-free cloth for cleaning. Do not use solvents or abrasive cleaners.
- Contact Wear: While designed for long electrical life, inspect contacts for excessive wear or pitting during scheduled shutdowns.

7. Troubleshooting
If the contactor is not functioning as expected, consider the following common issues:
- Contactor Fails to Energize:
- Check control circuit voltage (220 V AC).
- Verify control wiring connections (A1, A2).
- Inspect for open auxiliary contacts in the control circuit.
- Contactor Energizes but Load Does Not Operate:
- Check main power supply voltage.
- Verify power wiring connections (L1, L2, L3, T1, T2, T3).
- Inspect for open main contacts or overload conditions.
- Contactor Overheats:
- Ensure the load current does not exceed the rated operating current (40 A AC-3/AC-3e, 60 A AC-1).
- Check for proper ventilation around the contactor.
- Verify terminal connections are tight to prevent resistive heating.
- Excessive Noise/Chattering:
- Check for stable control voltage.
- Ensure the contactor is securely mounted.
If issues persist, consult a qualified electrician or refer to the detailed documentation available via the product's QR code.
