EATON CHB340 Type CHB Standard Molded Case Circuit Breaker, 240 V AC, 40 A, 10 kA Interrupt, 3 Poles, Thermal Magnetic Trip
Eaton's residential CH circuit breakers provide premium overload protection. The Type CH circuit breakers trip to the OFF position, eliminating nuisance callbacks. 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. Multiple breakers have an internal common trip connection to operate all poles simultaneously. Handles are marked with ON-OFF indication and ampere rating of the breaker.
