Type CH circuit breakers trip to the OFF position, eliminating nuisance callbacks. The thermal-magnetic trip curve avoids nuisance tripping on mild overloads while reacting almost instantaneously to severe short-circuit conditions. Multipole breakers have internal common trip connection to operate all poles simultaneously. Handles are marked with ON-OFF indication and ampere rating of the breaker. Special Application Plug-On Circuit Breakers Type CH 0 kaic 20 Vac and 20/240 Vac Branch Feeder Type Arc Fault Circuit Breakers A branch feeder type arc fault circuit interrupter is a device intended to mitigate high current arcing faults in the complete circuit, including connected cords. High current arcing faults can occur from line to neutral or line to ground. These arcing faults are in parallel with the load and produce the most energy of all arcing faults. The branch feeder type AFCI is required in the 999 and 2002 National Electrical Code. The Combination Type AFCI is required in the 2005 and 2008 National Electrical Code. Combination Type Arc Fault Circuit Breakers A combination type arc fault circuit interrupter is a device that includes all of the protection offered by the branch feeder AFCI (mitigation of high current arcing faults in the complete circuit, including connected cords). In addition it provides direct detection of persistent low current arcing faults down to 5 amps with associated mitigation of fire hazards in the cords connected to the outlets. High current arcing faults can occur from line to neutral or line to ground. These arcing faults are in parallel with the load and produce the most energy of all arcing faults. The current level of low current arcing faults is limited by the load. Ground Fault Circuit Breakers Ground Fault Application Notes Type CHGFIs are designed for use in two-wire, 20 Vac circuits. The diagram on Page V-T-39 shows a typical wiring configuration. Two-pole Type CHGFIs are designed for use in threewire, 20/240 Vac circuits, 20 Vac multiwire circuits employing common, neutral and two-wire, 240 Vac circuits obtained from a 20/240 Vac source. Diagrams on Page V-T-39 illustrate typical wiring configurations for 20/240 Vac multiwire circuits. The diagram on Page V-T-39 depicts a 240 Vac, two-wire circuit. Note the panel neutral conductor connects to the neutral bar, even though the neutral is not included in the load circuit. This connection is necessary to supply a 20 Vac power source to the ground fault sensing circuit. The figures are shown with a 20/240 Vac, single-phase, three-wire power source, but are also applicable to a 20/208 Vac, three-phase, four-wire power supply. For all figures, the electrical operation of the Type CHGFI is not affected by the equipment ground. Volume Residential and Light Commercial CA0800002E January 203 www.eaton.com V-T-29
