Add to Existing Equipment

A basic OPTIM Enclosed Breaker interior with a Series C N-frame Circuit Breaker and Digitrip OPTIM 750 Trip Unit. Each enclosure is delivered complete and pretested, ready for installation.

Economically Add to Existing Panelboards, Switchboards, and Motor Control Centers with Industry Leading Technology

The Digitrip® OPTIM™ programmable microprocessor-based trip unit is now provided in a factory assembled circuit breaker enclosure. This means you now have the capability to economically add superior programmable protection and coordination…plus the addition of a state-of-the-art advanced warning capability along with system diagnostics, monitoring, and communications.

OPTIM will enhance your distribution system by reducing downtime, managing energy costs, and helping you to utilize your equipment more efficiently. Enclosed circuit breakers equipped with OPTIM are suitable for use with new or pre-viously installed Cutler-Hammer panelboards, switchboards, and motor control centers …as well as those of other manufacturers.

Factory Assembled and Delivered Ready to Install

An OPTIM Enclosure includes a Digitrip OPTIM Trip Unit in either a Series C® L-frame at 125, 250, 400, or 600 amperes; or a Series C N-frame at 800 or 1200 amperes. Both enclosures are NEMA 12.

Optional Features Wired ground fault alarm relay. Hand held OPTIMizer programmer in a soft package. (Minimum of one required for initial address settings.) Advanced Enclosed Breaker Standard Feature Basic OPTIM plus a wired and mounted Breaker Interface Module. Optional Feature Mounted communications module.	Two OPTIM Enclosed Breakers: The advanced unit with Series C L-frame Breaker (left) and basic unit Series C N-frame Breaker (right). The L-frame enclosure is shown with a Breaker Interface Module mounted on the door. The N-frame enclosure shows a provision for future mounting of a Breaker Interface Module.	Digitrip OPTIM Trip Units can be programmed with the hand held OPTIMizer (left) that plugs into the front of the trip unit; or with the Breaker Interface Module mounted directly on the enclosure door.
	Digitrip OPTIM Trip Units utilize the proprietary SuRE Plus™ Chip microprocessor to provide unparalleled accuracy for protection, systems diagnostics, load monitoring, and communications. There are two OPTIM Trip Unit models…the 750 and the 1050; the 1050 monitors power, energy, and current harmonics.

Programmability Increases Protection and Coordination Capabilities

• Time-current settings with more increments that permit the user to OPTIMize system protection and coordination.
• Improved accuracy gives more selectivity and closer sensitivity in providing coordination.
• Improved reliability is provided by displaying time-current setpoints in actual amperes.
• Programmable short delay and/or instantaneous curve tripping options. Selectable powered and unpowered thermal memory as well as selectable sure start discriminator protection features.
• Increased system security is provided by the addition of programmable password protection. Application software packages are available to configure and download setpoints to provide faster, more efficient system management.

• I⁴t long delay time slope to the traditional nine LSIG curve shaping options.
• Short delay and ground delay zone selective interlocking down to a 70 ampere molded case circuit breaker.
