## Summary description

The Eaton U-PKZ0 is an undervoltage release designed for PKZ motor-protective circuit breakers. Operating at 230V 50Hz, this accessory ensures safety by automatically tripping the circuit breaker when the supply voltage drops below a specified threshold. It is a reliable component for industrial and commercial electrical systems, providing essential protection against voltage fluctuations and power loss.

## Long description

The Eaton U-PKZ0 undervoltage release is a specialized accessory designed for integration with PKZ and PKZM0 motor-protective circuit breakers. This device provides critical safety functionality by monitoring the supply voltage and automatically tripping the circuit breaker if the voltage falls below a predefined threshold. Engineered for reliability in industrial and commercial electrical environments, it serves as a vital component for protecting machinery and electrical systems against the risks associated with voltage drops and unexpected power loss.
Advantages
The primary benefit of the Eaton U-PKZ0 is its ability to prevent the automatic restart of motors after a power failure, which is essential for operational safety. By ensuring that the circuit breaker trips when voltage is insufficient, it protects sensitive equipment from potential damage caused by unstable power conditions. Its compact design allows for seamless installation within existing motor-protective circuit breaker configurations without requiring significant space or complex modifications to the electrical panel.
Suitable for
Industrial motor control centers
Commercial HVAC systems
Manufacturing machinery protection
Electrical distribution panels requiring undervoltage monitoring
When it may not be suitable
This device is not suitable for applications where voltage fluctuations are frequent and temporary, as it will cause the circuit breaker to trip unnecessarily. It is also not intended for use with circuit breakers outside of the specified PKZ and PKZM0 series.
Key specifications
Rated control supply voltage: 230V AC
Frequency: 50Hz
Compatibility: PKZ and PKZM0 motor-protective circuit breakers
Trip type: Non-delayed
How to use
The undervoltage release is installed directly into the designated slot on the side of the compatible PKZ or PKZM0 circuit breaker. Ensure that the main power supply is disconnected before attempting installation. Once the device is securely clicked into place, connect the control wiring to the terminals according to the electrical schematic. After installation, verify the connection by testing the trip function to ensure the circuit breaker responds correctly to voltage loss.
What to consider before purchase
Verify that your existing circuit breaker is a PKZ or PKZM0 model
Ensure your control circuit voltage matches the 230V 50Hz rating
Confirm that a non-delayed trip characteristic meets your safety requirements
Usage recommendations
Always perform a functional test after installation to confirm that the undervoltage release correctly trips the circuit breaker when power is removed. Ensure all wiring connections are tightened to the manufacturer's specified torque settings to prevent loose contacts.
