The PGR-6150 motor protection relay system from Littelfuse provides current- and temperature-based protection, metering, and data logging. The system is designed for low- to medium-horsepower three-phase motors in industrial environments and protects against overload, undercurrent, overcurrent, jam, overheating, phase loss, phase reverse, and phase unbalance. There are 13 protective functions that reduce or eliminate damage caused by electrical faults based on current and temperature inputs. The optional operator interface allows remote operation and field programming, and displays metered values. The product has a compact footprint and integrated current transformers. The wide adjustment range can accommodate different motor sizes and applications.
