Product Information

Full details

This Eaton PKZM0 circuit breaker is designed for industrial applications, offering reliable motor protection with adjustable overload and short-circuit settings. It's ideal for protecting electric motors in demanding environments. A key benefit is its phase failure sensitivity, ensuring motor safety under unbalanced power conditions. However, its specific current range (1.6-2.5A) means it's best suited for motors within this operational window.

Can this breaker be used for single-phase motors?

This breaker is specifically designed for three-phase motor protection and features phase failure sensitivity, making it most effective and intended for three-phase applications.

What is the breaking capacity of this circuit breaker?

The breaking capacity of this circuit breaker is 150 kA.

What type of terminals does it use?

It features screw terminals for secure connections.

How is the breaker mounted?

The breaker is designed for snap fitting onto a 45mm standard DIN rail.

Can I add accessories like auxiliary contacts?

Yes, this PKZM0 series breaker is compatible with auxiliary contact and voltage release accessories.

What is the operating temperature range?

The minimum operating temperature is -25°C and the maximum is +55°C.

Troubleshooting

Breaker trips immediately upon power-up

Check for a direct short circuit in the motor wiring or the motor itself. Verify the overload setting is not too low.

Breaker trips intermittently during normal operation

Verify the motor's actual operating current is within the breaker's set range. Check for mechanical issues causing increased load on the motor. Ensure ambient temperature is within operating limits.

Breaker does not trip when overload is applied

Ensure the overload setting is correctly calibrated. The breaker may be faulty and require replacement.

Phase failure protection not engaging

Confirm the unit is correctly wired for three-phase power. Check if the phase failure sensitivity feature is enabled/functional as per the manual.

Pros and Cons

Pros

  • Robust industrial-grade construction.
  • Precise motor protection through adjustable settings.
  • Enhanced safety features like phase failure sensitivity and finger-safe design.
  • Wide operating voltage range suitable for industrial settings.
  • Modular design allows for accessory integration.

Cons

  • Specific current range (1.6-2.5A) limits its application to matched motors.
  • IP20 rating offers limited protection against liquids or dust ingress.
  • Requires careful calibration of adjustable settings for optimal performance.
  • Not designed for domestic or light-duty applications.
  • Installation may require specialized electrical knowledge.

Setup, Compatibility & Care

Setup:

  1. Ensure the main power supply is de-energized.
  2. Mount the circuit breaker onto a standard 45mm DIN rail using the snap-fitting mechanism.
  3. Connect the motor power leads to the screw terminals according to the wiring diagram, ensuring correct phase sequencing.
  4. Adjust the overload setting dial to the motor's rated full-load current (within the 1.6-2.5A range).
  5. Install any optional accessories like auxiliary contacts or voltage releases as needed, following their specific instructions.
  6. Restore power and test the circuit breaker's functionality.

Compatibility:

  • Compatible with Eaton auxiliary contact modules (e.g., ZAV) and voltage release modules (e.g., ZU, ZS, ZHV).
  • Designed for use with motors operating within the 1.6A to 2.5A continuous current range.
  • Suitable for systems with a rated operating voltage of up to 690V AC.

Care:

  • Regularly inspect the breaker for signs of damage or overheating.
  • Keep the area around the breaker clean and free from dust and debris.
  • Periodically test the tripping mechanism according to maintenance schedules (consult local regulations or expert advice).
  • Use a dry, soft cloth for cleaning; avoid solvents or water.
