Cutler-Hammer PowerNet and Zone Interlock Kits (OPTIM 550 only) K-, L- and N-Frames
Figure 12-31. PowerNet Communication Kit
The Cutler-Hammer PowerNet Com-munications Kit can be ordered to add Cutler-Hammer PowerNet communica-tions to an existing OPTIM 550 breaker in the field. An 18-inch wiring pigtail is routed to the rear of the breaker: two wires for Cutler-Hammer PowerNet and two wires for 24V DC (45 mA load). It is recommended that the power supply be an “isolated high quality” unit.
Table 12-364. PowerNet and Zone Interlock Kits
1 Includes a ground fault alarm signal which can drive the Ground Fault Alarm unit (Catalog Number GFAU).
