The ABB PR222MP is an advanced Electronic Trip Unit (ETU) designed for ABB's Tmax XT series Molded Case Circuit Breakers (MCCBs) in the T4 to T7 frame sizes. It represents a significant upgrade from basic thermal-magnetic protection, offering a comprehensive suite of protection, measurement, and communication functions in a single, integrated unit. The "MP" suffix highlights its two core capabilities: M for advanced Measurement and energy metering, and P for Protection configurability via a front keypad.
