NEW TECHNOLOGY
Digitrip OPTIM is a new programmable
communicating microprocessor-based
low-voltage electronic trip unit system for
Westinghouse Series C Molded Case
Circuit Breakers and low-voltage power
breakers. Digitrip OPTIM trip units are
available in two styles, Digitrip OPTIM 750
and Digitrip OPTIM 1050, in Series C
frames L-, N-, and R-70 through 2500
amperes.
Digitrip OPTIM trip units are fully programmable
and can be applied as a
stand-alone breaker with a hand-held
Digitrip OPTIMizer programmer for configuring
the trip unit, displaying information
and testing. In addition, OPTIM can
be applied as a low-voltage assembly
with a panel mounted Breaker Interface
Module (BIM) to configure, display and
test. Alternatively, OPTIM can be applied
as part of a fully integrated IMPACC
system.

MOLDED CASE CIRCUIT BREAKERS
Digitrip OPTIM System
Stand Alone
The hand-held Digitrip OPTIMizer is used
to program individual OPTIM Trip Units.
Sub-Network
The Breaker Interface Module, mounted
on the assembly or at a remote location, is
used to access, configure, and display
information from Digitrip OPTIM Trip
Units. Any combination of OPTIM Trip
Units and/or Digitrip RMS 810/910 Trip
Units and/or IQ Energy Sentinels
(up to
50 devices) can communicate with the
Breaker Interface Module.
Field Bus
With Integrated Monitoring, Protection
and Control Communications (IMPACC),
the plant operator, facilities engineer, and/
or maintenance engineer can monitor and
control the entire power distribution system
from a central PC.

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
breaker status indications, controlled shutdown
sequence, monitoring, 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 economically
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 within sight of
motor loads.
