FAQs

What is the voltage and current rating of this switch?

This Eaton changeover switch is rated for 690V AC and 20A.

What type of actuator does this switch have?

It features a 3-position toggle actuator with a 45° angle.

What does the 'NO/NC' configuration mean?

NO/NC stands for Normally Open/Normally Closed. This indicates the state of the switch contacts when it is not activated, providing flexibility in circuit design.

What is the degree of protection for the front of the switch?

The front of the switch offers an IP65 degree of protection, meaning it is protected against dust ingress and low-pressure water jets.

What are the dimensions of the switch?

The dimensions of the switch are 137mm (height) x 80mm (width) x 137mm (depth).

Does this switch have an 'off' position?

Yes, this switch has a 4-step control that includes a dedicated 'off' position.

What type of terminals does it use?

It utilizes screw terminals for secure electrical connections.

Troubleshooting

Switch does not change state when actuator is moved.

Verify power is disconnected. Check for any mechanical obstructions. Ensure internal contacts are properly seated and wired. Consult the product manual for internal diagnostics if applicable.

Inconsistent contact behavior (e.g., intermittent connection).

Check the tightness of all screw terminal connections. Inspect contacts for wear or contamination and clean if necessary. Ensure the actuator is moving fully through its intended positions.

Overheating during operation.

Verify that the connected load does not exceed the switch's 20A rating. Ensure all connections are tight, as loose connections can cause resistance and heat. Confirm adequate ventilation around the switch if installed within an enclosure.

Pros and Cons

Pros

  • High voltage and current rating for robust performance.
  • Clear 4-step control with an 'off' position enhances safety.
  • Durable construction with IP65 front protection.
  • Flexible NO/NC contact configuration.
  • Reliable toggle actuator for intuitive operation.

Cons

  • Surface mount design may require specific enclosure preparation.
  • Dimensions might be larger than some compact switch alternatives.
  • Limited to 3 positions, which might not suit all complex switching needs.
  • Requires manual operation, not suitable for automated systems without additional controls.

Setup, Compatibility & Care

Setup:

  1. Ensure the power source is completely de-energized before installation.
  2. Mount the switch securely onto a suitable surface using appropriate hardware for its dimensions (137 x 80 x 137mm).
  3. Connect the electrical lines to the screw terminals according to your circuit diagram, ensuring correct wiring for the NO/NC configuration.
  4. Verify all connections are tight and secure.

Compatibility:

This switch is designed for AC circuits within its 690V AC and 20A rating. It is compatible with standard electrical enclosures and control systems that accommodate its physical dimensions and mounting type. Ensure the surrounding environment does not exceed the IP65 protection limits for the front face.

Care:

  • Periodically inspect the switch for any signs of damage or wear.
  • Keep the front face clean using a dry or slightly damp cloth. Avoid abrasive cleaners.
  • Ensure the area around the switch is free from excessive dust or moisture that could compromise the IP65 rating over time.
