NGB2B080B - 80 Amp Circuit Breaker

NGB2B080B - 80 Amp Circuit Breaker

The NGB2B080B is an 80-amp, 2-pole molded case circuit breaker for compatible NGB panelboard applications. If you're replacing an existing breaker, the important thing is getting the specifications right, and this unit has clearly defined ratings for easier comparison. It is rated 25k A.I.C. at 480VAC and 100k A.I.C. at 240VAC and measures 5.0 inches high, 2.0 inches wide, and 3.06 inches deep. The breaker is HACR-rated, has a 40.25°C rating, and comes with load-side terminals. Its panelboard-mount design makes the NGB2B080B a good fit for maintenance and replacement work in compatible legacy electrical systems. Compare the part number, amperage, number of poles, dimensions, mounting style, and electrical ratings with the breaker already in your equipment. When those requirements match, the NGB2B080B provides the form, fit, and function needed for the application. When properly installed and operated within its specified ratings, it is built to last.

Where It Works Best

• The NGB2B080B is intended for compatible panelboards and legacy electrical equipment that require an NGB-type 80A, 2-pole molded case circuit breaker. It's especially relevant when you need to replace an existing breaker while keeping the required physical and electrical configuration.
• Before installation, compare more than just the amperage. Check the NGB type, part number, two-pole configuration, A.I.C. and voltage ratings, dimensions, mounting method, and terminal requirements against the existing breaker and equipment specifications. A proper match is what matters most in a replacement application.
