Motor starter PKZM0, Ir=4-6.3A PKZM0-6.3-EA 189902

Motor starter – reliable protection for your installation

This three-pole motor starter PKZM0-6.3-EA from Eaton is a key element in protecting electric motors, providing protection against overloads and short circuits. The device is characterized by high reliability and a compact design, making it an ideal solution for both professional installers and end users. The rated continuous current of 6.3A and the short-circuit breaking capacity of up to 150kA at 400V AC guarantee effective protection in demanding working conditions.

Functionality and application

The PKZM0-6.3-EA starter is widely used in electrical circuits powering motors, transformers and other devices requiring protection against overloads and short circuits. Thanks to its phase failure sensitivity, it provides additional safety for the installation, minimizing the risk of damage caused by the absence of one of the phases. The rated operating power of 2.2 kW at 400V AC and 1.1 kW at 230V AC makes it a versatile device that can be used in various industrial and commercial applications. DIN rail mounting simplifies integration with existing electrical infrastructure.

Design and characteristic features

The starter has been designed with ease of installation and use in mind. Screw terminals provide a secure and durable connection of wires. Compact dimensions (93 mm height, 45 mm width and 76 mm depth) allow installation in limited space. The device meets IEC/EN 60947 standards, confirming its compliance with the highest standards of safety and quality. Additionally, the ability to connect to an MSFA adapter increases installation flexibility. The starter is a permanently mounted device and has a thermomagnetic tripping method – meaning a combination of thermal and magnetic protection in one device. Power losses are 5.68 W, which translates to efficient energy use.
