Motor Protective Circuit Breakers PKZ
The PKZ series from Moeller by Eaton integrates motor protection switches that combine overload protection and short-circuit protection in a single compact device. These are modular, high-breaking-capacity switches designed for switching and protecting motors and transformers. They are available in various frame sizes and amperage ratings, typically covering ranges from 0.1 A up to 63 A, with adjustable thermal overload settings and magnetic short-circuit releases. The PKZ series includes both basic and ZM variants, offering different levels of functionality such as integrated differential protection or additional auxiliary contacts. Their robust construction ensures reliable operation in continuous duty applications, making them a cornerstone for industrial motor control centers.
These devices are primarily installed in industrial control panels, motor control centers (MCCs), and distribution boards. They are essential for protecting three-phase induction motors in applications like pumps, fans, conveyors, and compressors. The PKZ switches are also used in transformer protection, HVAC systems, and machine tool electrical enclosures. Their modular design allows for easy integration into existing systems, and they are suitable for environments requiring high operational reliability, such as manufacturing plants, water treatment facilities, and automated production lines.
Key subcategories within the PKZ range include the PKZ0, PKZ2, and PKZM0 series. The PKZ0 is a compact size for lower current ranges (up to 16 A), while the PKZ2 handles higher currents (up to 63 A). The PKZM0 is a motor-protective circuit breaker with integrated differential protection. Typical article codes follow a pattern like PKZM0-16, PKZM0-25, PKZ2-32, or PKZ2-63, where the number indicates the rated current in amperes. Accessories such as auxiliary contact blocks (e.g., NHI-E, NHI-S) and undervoltage releases (e.g., UA) are also available to expand functionality.
