FAQs

What is the maximum switching current for this contactor?

The contactor has a maximum switching current of 40A at AC1 load type.

What type of contacts does the Eaton 248852 have?

It features 4 make contacts, which are normally open (4NO).

What control voltage is required for the coil?

The rated control circuit voltage is 230V AC. It is also compatible with 240V AC.

How is this contactor mounted?

It is designed for mounting on a standard 35mm top-hat (DIN) rail and has a mounting width of 3 SU (52.5mm).

What standards does this contactor comply with?

It adheres to IEC 61095, EN 61095, VDE 0660, IEC 60947-4-1, and EN 60947-4-1.

Can this contactor be used outdoors?

With an IP40 rating, it is suitable for indoor environments only and should be protected from moisture and excessive dust.

What is the contact material?

The contact material is Cadmium-free Ag-alloy, ensuring durability and reliability.

Troubleshooting

Contactor does not energize when control voltage is applied.

Verify that the control voltage is indeed 230V AC and is correctly applied to the coil terminals (A1/A2). Check for loose wiring or a blown fuse in the control circuit.

Contactor remains energized and does not de-energize.

Ensure the control voltage is removed. If the issue persists, the coil may be damaged, or there might be an external factor preventing de-energization. Inspect control circuit wiring.

Contacts are welded or not making proper connection.

This usually indicates the contactor has reached its end of life or has been subjected to overloads. The contactor will need to be replaced. Check if the load current exceeds the rated capacity.

Overheating of the contactor.

Verify that the load current does not exceed the 40A AC1 rating. Ensure proper ventilation around the contactor and that it is correctly mounted on the DIN rail for heat dissipation.

Pros and Cons

Pros

  • Robust switching capability for AC1 loads up to 40A.
  • Multiple (4) normally open contacts provide flexible control options.
  • Modular design and top-hat rail mounting simplify installation in control cabinets.
  • Compliance with major international electrical standards ensures reliability and safety.
  • Durable Ag-alloy contact material for long operational life.

Cons

  • Specific control voltage requirement (230V AC) limits universal application without transformers.
  • IP40 rating means it is not suitable for environments with excessive dust or moisture.
  • Requires careful consideration of the operating voltage range (195.5 - 253V AC).

Setup, Compatibility & Care

Setup:

  1. Ensure the power supply to the control circuit is de-energized.
  2. Mount the contactor onto a standard 35mm top-hat (DIN) rail using the integrated clips.
  3. Connect the control circuit wiring to the coil terminals (typically A1 and A2) based on the 230V AC requirement.
  4. Wire the main power circuits through the power terminals and the 4 NO contacts according to your schematic.
  5. Ensure all connections are secure using the screw terminals.

Compatibility:

  • Control Voltage: Primarily compatible with 230V AC or 240V AC control circuits. Ensure your control system provides this voltage.
  • Mounting: Designed for standard 35mm top-hat (DIN) rail mounting.
  • Environmental: Suitable for indoor environments with an IP40 rating. Avoid excessively dusty or humid locations.
  • Standards: Complies with IEC 61095, EN 61095, VDE 0660, IEC 60947-4-1, and EN 60947-4-1.

Care:

  • Regularly inspect connections for tightness and signs of wear or overheating.
  • Keep the contactor free from dust and debris, particularly around the moving parts and coils. Use a dry cloth for cleaning; avoid solvents.
  • Ensure adequate ventilation around the contactor to prevent overheating, especially under high load conditions.
  • Periodically test the operation of the contactor to ensure proper switching.
