Current limiter 3-pole CL-PKZ0 082881

Short-circuit current limiter – protection and reliability of the installation

This three-pole current limiter CL-PKZ0 from Eaton is a key element ensuring safety and reliability in electrical installations. Designed for mounting on a DIN rail, it provides effective protection against overvoltage and short circuits, minimizing the risk of equipment damage and power outages. It is compatible with protective switches of the PKZM0, PKZM4 and PKZM01 series, making it a universal solution for a wide range of applications.

Functionality and application

The CL-PKZ0 current limiter is designed to work with overcurrent switches, enhancing their operation and providing a faster response in the event of dangerous conditions in the installation. Its task is to limit the value of the short-circuit current, which allows minimizing the load on the remaining elements of the electrical system. The rated continuous current at 63A makes it an ideal solution for circuits with medium load.

• Short-circuit protection: effectively limits the effects of overvoltage and short circuits, protecting devices connected to the installation.
• DIN rail mounting: ensures easy and quick mounting in electrical switchboards.
• Compatibility: works with popular Eaton switch series (PKZM0, PKZM4, PKZM01).
• Application: ideal for securing circuits in residential, commercial buildings and industrial installations.
• High reliability: made of high-quality materials guarantees long-lasting and trouble-free operation.

Characteristics and benefits

The CL-PKZ0 current limiter is not only a protective element, but also an investment in the long-term stability and safety of the electrical installation. The lack of a rated conditional short-circuit current (Iq = 0 kA) indicates its specialized purpose – limiting the current and not completely disconnecting the circuit as in the case of traditional circuit breakers. This avoids unnecessary downtime caused by false tripping, especially when starting devices with high inrush current. Installing this limiter increases the resistance of the entire installation to sudden voltage and current surges, which translates into a longer service life of connected devices.
