This Moeller PKZM0-6,3 is a used motor protection switch — sometimes referred to as a motor circuit breaker — offered here within the laboratory equipment category. Devices of this type are designed to protect three-phase motors against overload, short circuit, and phase failure, making them a fundamental component in mechanical engineering, switchgear construction, and industrial control systems. Moeller, now part of the Eaton group, is a well-established German manufacturer with a long track record in electrical protection and control technology serving industrial and commercial markets worldwide.
The unit provides thermal-magnetic tripping with an adjustable nominal current range of 4.0 to 6.3 A, covering a broad spread of small motor applications. It is rated for voltages up to 690 V AC and, depending on the upstream fuse, offers a switching capacity of up to 150 kA. The switch is three-pole and mounts directly onto a standard DIN rail, making integration into existing control cabinet layouts straightforward. Protection is rated at IP20 on the front face.
Operationally, the device combines overload and short-circuit protection in a single compact unit, eliminating the need for separate protective components. It features a manually operated on/off switch with a locking function, a test button for in-situ functional verification, and a plain-text scale for clear current-setting readability. The switch position is clearly identifiable at a glance. It is also compatible with auxiliary switches and fuse combinations for expanded circuit protection configurations.
The device is supplied used and in good functional condition, with light signs of wear. It is described as ready for immediate use. Origin is listed as Made in Germany, and the unit is located in Germany, priced at $18.
