The Eaton Cutler-Hammer ZM-16-PKZ2 solid-state overload is essential for motor protection in various applications. This component has a compact weight of 0.40 lbs. It can handle a rated uninterrupted current of 16 A.
The settings for overload release span from 10 A to 16 A, making it versatile for different motor applications. Users can adjust the overload release to operate between 0.6 to 1.0 times the uninterrupted current, providing additional customization. For short-circuit protection, the settings range from 130 A to 220 A; this feature ensures reliable operation under fault conditions and comes factory-set at 12 times the rated uninterrupted current.
In terms of capability, the ZM-16-PKZ2 can support maximum motor power ratings depending on the voltage. It accommodates up to 4 kW at 220-240 Volts AC-3, 7.5 kW at 380-415 Volts AC-3, and maintains 9 kW at both 440 and 500 Volts AC-3. For higher voltage scenarios, it can handle up to 12.5 kW at 660-690 Volts AC-3.
The device is configured with three poles, providing the necessary connections for motor control systems. Additionally, its impulse withstand voltage rating of 6000 V adds to its reliability, protecting the device and connected equipment from voltage transients.
