Motor starter switch 4A 1.5kW with push-button drive PKZM01-4 278482

Motor starter – reliable protection for your devices

This three-pole PKZM0-4 motor starter from Eaton is a key element in protecting the electrical installation powering motors. It provides effective protection against overload and short circuit, minimizing the risk of damage and downtime. Designed for reliability and durability, it will work well in both professional applications and home workshops.

Functionality and parameters

The starter is characterized by an adjustable overload release in the range of 2.5 – 4 A, which allows for precise adjustment to the load characteristics. The rated operating power for AC-3 is 1.5 kW at 400 V, and the high short-circuit breaking capacity (50 kA at 400 V) guarantees safety even in the event of serious disturbances. Additionally, the built-in phase failure sensitivity protects the motor against damage caused by the absence of one of the supply phases. Mounting is done using screw connections, which ensures a stable and reliable connection of the wires.
