OVERVIEW
Quick-make, quick-break switch mechanism combined with inverse time element tripping operation and tripfree handle design. 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 10 kAIC 120 Vac and 120/240 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+L1491 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 1999 and 2002 National Electrical Code. The Combination Type AFCI is required in the 2005 and 2008 National Electrical Code.
