Motor Protection IMM7960 / IMM7990
The IMM7960/IMM7990 relays protect HV, MV and high-power LV motors. Thermal protection is provided via a thermal "image" as these devices do not support temperature sensors.
The IMM7960 (pictured left top) is a compact relay with ANSI functions:
37 I / 50 / 46 / 51LR / 49 / 51N
The IMM7990 (pictured left bottom) is a larger alternative with more functions:
37 I / 51 LR / 46 / 51N / 48 / 49 / 50 / 5/49 / 5/66 + thermal pre-alarm
These relays are part of the PROCOM range, offering multi-function protection and communication via Modbus (RS485). A full brochure is available on the PROCOM range page
