Stocking a lot of devices with different over-current and short circuit trip characteristics is an expensive task. Even if you did, the time it takes rewiring devices to accommodate application changes is an avoidable waste. The PKZ2 is the first self-protected combination controller in the industry with interchangeable and adjustable, “tool-less,” plug-in trip modules. Eleven different ZM-PKZ2 modules cover the range from fractional to 30 HP at 460V AC (25HP @ 600V AC). Exchanging trip modules can be done in seconds… without rewiring power conductors.
