Description Place of Origin : China Brand Name : OEM brand Model Number : CH320 CH330 CH340 CH350 CH360 CH370 CH3100 Type : Mini Poles Number : 3 Rated Voltage : 240V BCD Curve : C Rated Frequency : 50/60hz CH320 CH330 CH340 CH350 CH360 CH370 CH3100 20A 30A 40A 50A 60A 70A 100A 3P 3 Pole 10kA Thermal Magnetic Circuit Breaker   Circuit BreakersQuick-make, quick-break switch mechanism combined with inverse time element tripping operation and tripfree handle design. This type 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. 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.   Plug-on Circuit Breakers   Ampere Rating Catalog Number Single-Pole120/240 Vac Two-Pole120/240 Vac Three-Pole240 Vac 10A CH110 CH210 CH310 15A CH115 CH215 CH315 20A CH120 CH220 CH320 25A CH125 CH225 CH325 30A CH130 CH230 CH330 35A CH135 CH235 CH335 40A CH140 CH240 CH340 45A CH145 CH245 CH345 50A CH150 CH250 CH350 60A CH160 CH260 CH360 70A CH170 CH270 CH370 80A   CH280 CH380 90A   CH290 CH390 100A   CH2100 CH3100
