Instantaneous voltage loss trigger U-PKZ0(230V50HZ) 073135

Undervoltage release for circuit breakers – reliable installation protection

The instantaneous undervoltage release U-PKZ0(230V50HZ) is a protective element designed for mounting in motor starters of the PKZ0(4) and PKE series. Its function is to quickly disconnect the power supply in the event of a voltage drop, minimizing the risk of damage and ensuring safe operation. This device finds application in both industrial installations and commercial buildings, where reliability and protection against failures are crucial.

Functionality and application

This undervoltage release is mounted on the left side of the circuit breaker and enables the implementation of emergency shutdown or stop functions in accordance with IEC/EN 60204. This ensures compliance with safety requirements in various applications. Its construction based on screw connections provides a solid and durable electrical connection. The device is dedicated to working with a voltage of AC 230V/50Hz, making it an ideal solution for most standard electrical installations in Poland.

Advantages and benefits

• Fast response: The instantaneous nature of operation guarantees immediate power disconnection in the event of a voltage drop, protecting connected devices from damage.
• Versatility: Compatibility with PKZ0(4) and PKE series circuit breakers means the release can be used in a wide range of applications.
• Safety: Compliance with IEC/EN 60204 ensures a high level of safety for the electrical installation.
• Simple installation: Mounting on the left side of the circuit breaker is intuitive and does not require specialized tools.
• Common accessories: The ability to use common accessories for the PKZM0/PKZM01/PKZM4 series (releases, auxiliary contacts) simplifies inventory management and reduces operating costs.
• Solid connections: Screw connections provide reliable and durable electrical connections, minimizing the risk of failures caused by loose connections.

The rated AC voltage is 230 V, and the frequency is 50 Hz. The release operates with AC control voltage and has screw connections. Its main function is emergency shutdown or stop.

It is worth remembering that this release does not have a time delay, which means its immediate reaction to a voltage drop. This is particularly important in applications where rapid power disconnection is critical for safety and equipment protection.
