The CNDC312T107W circuit breaker is a Series C molded case circuit breaker manufactured by Eaton. It is rated 600 Volts AC and 1200 Amps, and it has 3 poles. It features an N-frame and its ultra-high interrupting capacity is rated 100 kAIC at 480 Volts AC. The trip model that is available on this circuit breaker is the OPTIM 1050 and it is designed to protect equipment and conductors against short circuits, overloading, and fault currents in low-voltage distribution systems. The width of this unit is 8.25 inches, its height is 8.25 inches, its depth/length is 5.5 inches and it weighs 20.4 kilograms. An electronic LSIA trip type is available on the CNDC312T107W molded case circuit breaker, so it offers adjustable instantaneous pickup, adjustable short delay pickup, adjustable ground-fault alarm, and adjustable long delay pickup.
The CNDC312T107W circuit breaker features a toggle-type switch that is mechanically trip-free from the handle in order to ensure the contacts of the circuit breaker open even if the switch is locked in the ON position when a fault occurs. The position of the switch clearly indicates whether the breaker has been tripped as a result of short circuits, overcurrents, or overloads. After this circuit breaker trips, it must be reset manually before resuming operation. The high-repulsion contacts built into the CNDC312T107W molded case circuit breaker as well as its fast blow-open capability prevent jams in the switch mechanism when faults occur. This unit is compatible with a variety of field-installable accessories to meet specific application needs. Note that terminals do not ship with this unit.
