3-pole motor circuit breaker 0.75kW 1.6-2.5A 199154

The PKZM0-2.5-PI is a three-pole motor circuit breaker designed to protect electric drives against overloads, short circuits, and phase failure. The device utilizes a thermomagnetic tripping mechanism that responds to both long-term overloads and short-circuits. An overload current adjustment range of 1.6 to 2.5 A allows for precise adjustment to the specific application and motor parameters. The maximum rated power at 400 V AC (AC-3 category) is 0.75 kW, while the maximum operating voltage reaches 690 V, allowing for wide use in industrial environments. The device is equipped with Push-In technology, enabling quick and secure cable connection without tools, reducing installation time. An additional advantage is the built-in phase failure sensitivity, providing significant protection for three-phase motors. The circuit breaker also has a high Icu short-circuit breaking capacity of 150 kA, ensuring effective operation even in the event of a short circuit. The housing's IP rating is IP20, providing basic protection against contact and foreign bodies larger than 12.5 mm in diameter. The device's rated continuous current (Iu) is 2.5 A, confirming its versatility in protecting various types of electric drives in industrial automation and technical installations.
