The MPU-32-00-01 is a motor protection unit designed for three-phase, low-voltage, medium-horsepower induction motors, providing current and temperature-based protection, metering, and data logging. It accepts onboard 1-A phase current transformer inputs, operates on 65-265 V ac or 80-275 V dc, and includes standard TIA-232 communication. The unit features three programmable Form C output relays, a 4-20 mA analog output, and conformal coating. It supports protective functions including overload, ground fault, phase loss, unbalance, temperature protection via RTD or PTC, and starts per hour. Mounting is panel mount standard, with optional surface mounting via the MPU-32-SMK kit. It is certified to CSA, UL, CE, and RCM standards and carries a 10-year warranty.
The MPU-32-00-01 is a motor protection unit with a supply voltage between 65–265 V ac and 80–275 V dc. This unit provides current and temperature-based protection with communication via RS/TIA-232.
