Equipment Description
Overview This chapter describes the features of the GE Multilin to Bulletin 825 Plus
Conversion Kit.
Operational Requirements Monitoring application parameters and process data of an installation is very
important. Even a slight change in the starting and operating behavior of the
motor can indicate an impeding fault. The Bulletin 825 Plus helps eliminate
the potential trouble before major repairs are necessary and loss of production
occurs.
The Bulletin 825 Plus fulfills these requirements by providing the following
protective functions:
• High overload, stalling
• Underloading
• Wrong direction of rotation
However, the Bulletin 825 Plus functionality does not directly correspond to the
GE Multilin relays. Below is a summary of some of the features offered by the
Bulletin 825 Plus.
