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.
