The Eaton Cutler-Hammer NGH312035E Electronic Circuit Breaker is a compactly designed Frame NG breaker in the G Series of breakers with the DigiTrip 310 plus electronic trip unit that is used for enhanced circuit protection in applications requiring high levels of system coordination. By design, the NGH312035E offers space-saving features with very compact components that can be field-installed, and it is rated for reverse feed use and HACR-rated systems. It offers true RMS current sensing capabilities for very accurate and reliable circuit protection, and it is designed to protect the entire breaker from excessive temperature damage using its built-in over temperature trip. The NGH312035E has a 1200 Amps nominal current rating that is suitable for most 600 Volts AC applications, and it offers 65 kAIC of maximum interrupting capacity at 460 Volts AC input.
It has 3-pole wiring with imperial tapped line and load end terminal options, and it comes with LED status indicators, which only show the operation status. The NGH312035E has adjustable ground fault, long-time, and short-time pickup settings, and it is designed with an instantaneous override setting with a value just below the nominal rating for added protection. Its long delay pick is adjustable from 0.5 to 1.0% of the plug rating, and its ground fault pickup setting is adjustable from 1 to 5% of the ground fault maximum rating (160 Amps). This breaker is designed to hold the ground fault for a maximum of 500 milliseconds before tripping, and it has a long delay timing setting of up to 12 seconds. The NGH312035E is designed to automatically adjust the trip timing in the event of future current condition exceeding the pickup set point, and it achieves this by using the built-in thermal memory, which stores and remembers recent trip timings. The NGH312035E is designed to meet the UL and IEC standards, and it is supplied with standard mounting dimensions of 8.25 x 16.0 x 5.50 inches and with a net weight of 45.0 pounds.
