Quick make, quick break switch mechanism combined with inverse time element tripping operation and trip-free handle design. Type CH circuit breakers trip to the off position, eliminating nuisance call backs. The CHF family also includes a trip flag to differentiate between a trip and the breaker being turned off. The thermal magnetic trip curve avoids nuisance tripping on mild overloads while reacting almost instantaneously to severe short circuit conditions. Multi-pole breakers have internal common trip connection to operate all poles simultaneously. Handles are marked with on off indication and ampere rating of the breaker.

Cutler-Hammer Circuit Breaker, 30 A, 120/240 VAC, 10 kA Interrupt Rating, 2 Poles, 1 ph Phase, (1) 14 to 8 AWG, (2) 14 to 10 AWG Wire, Plug-On Mounting, 60 to 75 deg C, 3/4 in Width, 3 in Length, 3-1/2 in Height

• Common trip requires two 3/4 in spaces
• For two-pole circuit breakers carry listing for HACR application
