Module, and the optional IMPACC software form a sys-
tem that is capable of:
• Setting trip units
• Configuring systems
• Monitoring/protecting
• Displaying information
• Diagnosing input
• Testing trip units/circuit breakers
• Communicating on sub-networks/networks
Application of low voltage circuit breakers utilizing
OPTIM Trip Units generally fall into three primary cate-
gories:
Stand Alone Application (Individual Circuit
Breakers)
These applications are utilized to take advantage of the
superior protection and coordination features of Digitrip
OPTIM, and plan to perform monitoring at the circuit
breaker itself (Figure 1-6).
The following would be used:
• OPTIM 550, 750 and/or 1050 Trip Units
• One or more OPTIMizer Hand Held Programmers
Integrated Assembly Applications (Low Voltage
Assemblies)
These applications are utilized to provide on-gear or
remote monitoring and even testing of compatible
devices (Figure 1-7). Up to 50 OPTIM Trip Units, Digitrip
RMS 810/910 Trip Units or IQ Energy Sentinels can
communicate with one Breaker Interface Module.
The following would be used:
• OPTIM 550 (if field IMPACC kit installed)
• OPTIM 750 and/or 1050 Trip Units
• Digitrip RMS 810 and/or 910 Trip Units
• IQ Energy Sentinels
• One or more OPTIMizer Hand Held Programmers
• One or more assembly/remotely mounted Breaker
Interface Modules
Facility Wide Application (IMPACC System)
These applications are utilized to tie together more than
50 circuit breakers and/or other compatible devices. In
addition, this permits taking advantage of PC-based
software to improve diagnostics, power quality and
energy monitoring, or protective device coordination
capabilities. The system would consist of any number of
devices and software products, either within a facility or
across multiple facilities (Figure 1-8).
