The MPU-32-01-01 is a three-phase motor protection unit that provides current and temperature-based protection, metering, and data-logging for low-voltage induction motors. It supports standard TIA-232 and optional TIA-485 communications, and operates from 65-265 V ac or 80-275 V dc. The unit includes three programmable Form C output relays, a 4-20 mA analog output, an onboard RTD input, and a 24 V dc source for digital inputs. It is conformally coated and mounts on a panel. The relay accepts 1-A secondary current transformer inputs and supports protective functions per IEEE 46, 49, 50, 51, 37, 38, 50G/N, 51G/N, 66, and 87. It is CSA, UL, and CE certified, with a 10-year warranty.
The MPU-32-01-01 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-RS/TIA-48
