Design Capabilities
Pow-R-Line i compartmentalized switchboards are engineered for applications where a greater degree of safety is required. These switchboards are rear accessible and utilize the full family of Cutler-Hammer molded case circuit breakers and fusible switches.
Design capabilities are enhanced by a wide range of available main devices, utility provisions, and customer metering arrangements.

Increased Safety Features
- Compartmentalized design for use where a greater degree of safety is required.
- Individual compartments for branch devices – glass polyester for breakers and steel for fusible switches. Compartments help eliminate possible contact with the main bus and reduce fault propagation.
- Three section construction with each barriered from the other.
- Device Section. Each device is mounted in its own compartment.
- Bus Bar Section. Contains both horizontal and vertical busses.
- Rear Cable Compartment. Com pletely isolated from the bus bars.
- Insulated copper runback. Power taken from the protective device by the runback through a standard full height glass polyester barrier to the rear cable compartment, virtually eliminating the possibility of accidental contact with the main busses during installation or maintenance.

Optional Features
 |
Five L- or N-frame breakers with Digitrip OPTIM Trip Units and one Breaker Interface Module can be mounted in a single 45-inch (1143.00-mm) wide distribution structure. Six L- or N-frame breakers can be mounted when the Breaker Interface Module is mounted in another section or is not required. |
|
Digitrip OPTIM Trip Units are wired at the factory to customer specifications and are shipped ready for customer programming. |
 |
 |
Digitrip OPTIM Trip Units can be easily programmed and monitored at the switchboard using the hand held OPTIMizer. |
