Eaton PKZM0 Motor Starters – Reliable Motor Protection

The PKZM0-20 motor starter is a protection device designed to protect electric motors against overloads, short circuits, and phase failure. The device, with a rated current of 20A and a power of 9kW (AC-3, 400V), finds application in a wide range of industrial and commercial applications. The construction based on proven Eaton technology guarantees high reliability and long life.

Functionality and Safety

The PKZM0-20 starter is characterized by sensitivity to phase failure, which minimizes the risk of motor damage in the event of voltage asymmetry. The rated short-circuit breaking capacity Icu at 50kA at 400V ensures effective protection of the installation in the event of a short circuit. The adjustable overload release range (16-20A) allows for precise adaptation to the load characteristics. Mounting is done on a standard DIN rail, and the connection of wires is realized with screw terminals, which ensures a stable and safe connection.

Design and Application

The starter is designed to operate in harsh industrial conditions, with a wide range of operating temperatures (-25°C to +55°C). Compact dimensions (45mm x 93mm x 76mm) allow for easy integration with existing switchboards. The device complies with IEC/EN60947 standards, which confirms its safety and quality. Thanks to its versatility, the PKZM0-20 starter can be used in various types of motor loads, providing comprehensive protection and reliable operation. The use of a thermal-magnetic tripping method guarantees a quick reaction to overloads and short circuits.
