Motor starter switch 2.5A 0.75kW with push-button drive PKZM01-2.5 278481

Motor starters – reliable protection for your devices

This three-pole motor starter PKZM01-2.5 from Eaton Electric is a key element in protecting electric motors in industrial and commercial installations. It provides effective protection against overload, short circuit and phase failure, minimizing the risk of damage and downtime. The device is characterized by a high short-circuit breaking capacity – up to 50 kA at 400 V, which guarantees safety even in demanding working conditions.

Functionality and application

The starter is designed for mounting on a DIN rail and connection using screw connections. It has an adjustable overload release in the range of 1.6…2.5 A, which allows for precise adjustment to the characteristics of the protected motor. Phase failure sensitivity further increases safety by protecting the motor from incorrect operation in the event of a loss of one of the phases. The rated operating power for AC-3 is 0.75 kW at 400 V and 0.37 kW at 230 V, making it an ideal solution for motors up to 0.75 kW.

Construction and characteristic features

The PKZM01-2.5 starter is distinguished by its compact design with dimensions of 90 mm (height) x 45 mm (width) x 93 mm (depth). The IP20 degree of protection provides basic protection against touch and contamination. The device is intended for the construction of permanently mounted equipment and has a thermal-magnetic release method. It is worth emphasizing the compatibility of accessories with the PKZM0 and PKZM01 series – undervoltage releases, auxiliary side and front contacts, and release indicators are mutually interchangeable, which facilitates servicing and expansion of the installation. Additionally, IP65 enclosures with an emergency mushroom head or membrane are available to increase safety in difficult environmental conditions.
