The Eaton Cutler-Hammer NGC308032E Molded Case Circuit Breaker is a completely assembled Frame NG circuit breaker with a digital trip unit used for enhanced and accurate overload protection in a variety of applications with high standard and coordination need requirements. It has an electronic trip unit with microprocessor-based RMS current sensing for proper correlation with the thermal characteristics of conductors and equipment, and it has an over-temperature protective feature, which provides added protection in the event that the operating temperature rises above the designated value. The NGC308032E has a current rating of 800 Amps, with a current interrupting limit of 100 kAIC at 480 Volts, and it has a UL-rated line voltage of 600 Volts AC across its terminals. It features the state-of-the-art high-speed blow open contact which keeps the contact from closing in the event of an abnormal circuit condition by using electromechanical force, and it has a hand toggle operating mechanism which indicates the breaker’s position. It has 6 function current settings that are adjustable via a front-mounted switch, and it has a 3-pole wire design with a trip element and trip bar on each pole.

The NGC308032E has a load and line end imperial tapped terminal option made of copper/aluminum conductors, and it is supplied with imperial mounting hardware for easy installation. It features ground fault long-time and short-time pickup setting, and an instantaneous override switch with a rating just below the breaker’s nominal rating for additional protection. The NGC308032E has an average long delay time of 15 seconds, with 0 to 100 milliseconds of short delay time, and it has a thermal memory capable of remembering the timing sequence of recent abnormal circuit conditions, and it is capable of imposing shorter delay timing on subsequent conditions. The NGC308032E has LED status indicators that cannot indicate the cause of faults, and it is shipped with a standard test kit for field testing. It has a standard 40 degrees Celsius calibrated temperature limit with a 100% rating, and it is used within a 0 to 95% non-condensing relative humidity range. It has an approximate mounting weight of 20.4 kilograms (45 pounds), with aggregate dimensions of 209.60 x 406.40 x 139.70 millimeters (8.3 x 16.0 x 5.5 inches) and it is UL, IEC, and CSA certified.
