About NGH312039E

The Eaton Cutler-Hammer NGH312039E Frame NG Electronic Circuit Breaker is a current limiting breaker with electronic trip units that is used for providing short-circuit and overload protection to conductors and the connected electrical devices. This breaker is designed with imperial load and line side terminals with a 3-pole wiring configuration, and it provides easy mounting using the supplied imperial mounting hardware. It has a nominal current rating of 1200 Amps, with an interrupt capacity of 65 kAIC, and it is suitable for low-voltage applications with 600 Volts AC of maximum operating voltage. The NGH312039E comes with a true RMS current sensing trip unit for enhanced protection and with an embedded system maintenance mode. Like all breakers with electronic trip units, the NGH312039E offers a built-in over temperature trip, with all-around protection for excessive temperature situations. The NGH312039E’s trip unit is designed to provide microprocessor-based protection in systems requiring accurate high coordination, and it has up to 6 current settings that are electronically adjusted using programming devices.

Its trip units have adjustable long time, short time, instantaneous, ground fault pickup settings, and a discriminator circuit which protect the users from hazardous electric shocks as well as making sure that the trip unit functions within the designated parameters. The NGH312039E has a long delay time of 2 to 24 seconds, with a short delay time that is electronically adjusted from 100 to 500 milliseconds and it has a built-in thermal memory which remembers the timing sequence of past overloads and imposes shorter delay timing upon subsequent overloads. For additional protection, there is an instantaneous override with a set value below the breaker’s continuous current rating, and it comes with LED indicators which show fault statuses as well as the causes of faults. The NGH312039E offers digital system monitoring via an optional digital display, and it is shipped with a standard test kit. It has an ambient temperature limit of 40 degrees Celsius, and it can operate optimally at a maximum height of 6000 feet. The NGH312039E has an approximate shipping weight of 20.4 kilograms, and total shipping dimensions of 210.6 x 406 x 140 millimeters.
