Advance Warning Alerts to Potential Problems

• A programmable high load phase and neutral alarm, adjustable between 50 percent and 100 percent of Ir (LDPU setting), will signal an impending trip condition.
• An adjustable ground fault alarm that will alert the user of a ground fault condition without tripping the breaker.
• Energy alarming can be performed (such as peak demand exceeded) to reduce energy costs with OPTIM 1050 via IMPACC.
• THD alarming detects changes in power quality with OPTIM 1050 via IMPACC.

System Diagnostics Provide Reduced Downtime

Four cause of trip LEDs are mounted on the front of the trip unit to improve trouble- shooting capabilities. They are complement-ed by trip event information that is stored in memory after a trip condition.

Remote breaker status indicator is provided by auxiliary and alarm switches.

The Breaker Interface Module provides trip indication information on the front of the unit itself or via relay contacts to a re--mote location.

System Monitoring – "If You Can't Measure It, You Can't Manage It"

Digitrip OPTIM has an extensive menu of system monitoring capabilities:

• Load monitoring (ABCNG).
• Power factor (OPTIM 1050).
• Power and energy (OPTIM 1050).
• Power quality – current harmonics (OPTIM 1050). Accuracy based on full scale sensor rating:
  • ± 2% Current.
  • ± 4% Power.
  • ± 5% Energy.

System Communications

OPTIM Trip Units are IMPACC compatible and can be included in the unique Cutler-Hammer IMPACC communications system, specially designed for electrical distribution applications. All OPTIM programming, configuration, advanced warning, diagnostics, monitoring, and control capabilities can be accessed from a central PC using IMPACC software. Additional software packages can provide energy management as well as waveform capture.

Field Testing to Verify Performance

Trip or no trip testing can be performed on OPTIM Trip Units to verify operation. Testing can be completed by using a Digitrip OPTIMizer, the Breaker Interface Module, or IMPACC software. An auxiliary power module can be provided for bench testing.

Typical OPTIM Applications

When more information is required to better manage your production process. In a critical process such as a batch reactor used in the food, chemical, pharmaceutical, and petroleum industries.

Material in the process vessel can be worth more than the equipment required to produce it. This application requires close coordination with the overall electrical distribution system, possible isolation from the main switchboard, higher levels of overload and fault protection, remote break-er status indications, controlled shutdown sequence, mon-itoring, and data collection.

When early warning information that reduces downtime is required. On a critical production line such as an automatic feeder supplying subassemblies for a finished product used in the automotive industry, or by OEMs and electric product manufacturers. Automated welding and paint lines, for example, require higher levels of overload and fault protection, advanced warning of an impending trip condition, and system diagnostics which reduce the time necessary to get back on line.

When there is a concern with system obsolescence. When upgrading your facility's electrical distribution system, there could be a requirement to replace obsolete main or branch protection devices where space is limited. Feeders for laboratories and computer rooms could require better coordination and protection, while specialized equipment such as engine generators and variable frequency drives could also require upgraded protection.

OPTIM meets these requirements eco-nomically…because they provide high reliability and increased performance in a compact, dustproof unit that is wall mountable. Rewiring costs are minimized. A Digitrip OPTIM Enclosed Circuit Breaker can be locked in the off position to comply with OSHA lockout/tagout regulations, and meet the NEC 430 requirements for a separate disconnect means within sight of motor loads.
