The PKZM0-1,6-PI model is a key component in modern electrical systems, enabling effective motor management and protection against overloads and damage. This three-pole device utilizes a thermomagnetic tripping mechanism that responds to both sustained overloads and short circuits. One of the key advantages of this circuit breaker is the ability to precisely adjust the overload current within a range of 1 to 1.6 A, allowing it to be tailored to the specific application and system characteristics. This model does not include a built-in auxiliary contact or undervoltage release, but this does not affect its functionality. It is worth noting its favorable technical parameters – the rated power at 400 V, in the AC-3 category, is 0.55 kW, while the maximum operating voltage reaches 690 V, making it suitable for a wide range of industrial applications. The circuit breaker also stands out for its robust construction and very simple installation thanks to Push-In technology, which allows for quick, tool-free wiring, saving time during installation. It is also worth mentioning the rated continuous current (Iu) of 1.6 A, which further highlights the universality of this solution in protecting various types of electric drives – both in industry and in other technical environments.
