- Quick-make, quick-break switch mechanism combined with inverse time element tripping operation and tripfree handle design
- Switching Duty Rated, Heating and Air Conditioning Rated
- 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
