NGB1B080B - 80 Amp Circuit Breaker

NGB1B080B - 80 Amp Circuit Breaker

When you’re replacing a circuit breaker in an existing panelboard, the details matter. The NGB1B080B is an 80-amp, 1-pole Type NGB molded case circuit breaker designed for compatible panelboard applications. It measures 5.0 inches high, 1.0 inch wide, and 3.06 inches deep, making it easy to compare its physical size with the breaker already in your equipment. The electrical ratings are just as important: this model is rated 25kA at 277VAC and 100kA at 120VAC. It is also HACR-rated, carries a 40.25°C rating, and includes load-side terminals. For maintenance work on legacy electrical equipment, the NGB1B080B can be a practical form, fit, and function replacement when these specifications match the original breaker and panelboard requirements. Rather than choosing by appearance alone, check the part number, amperage, number of poles, mounting style, dimensions, voltage, and interrupting rating. It’s a straightforward molded case breaker built to last when installed correctly and used within its specified ratings.

Key Features and Benefits

• 80 amp rating for compatible circuits requiring an 80A breaker.
• 1-pole configuration for equipment designed around a single-pole NGB breaker.
• Type NGB molded case design for use with compatible panelboard equipment.
• 25kA at 277VAC and 100kA at 120VAC A.I.C. ratings clearly specify the breaker for the application.
• HACR is rated for applications that require this rating and compatible remaining equipment specifications.
• Panelboard mount configuration.
• Load-side terminals included with the breaker.
• At just 1 inch wide, its dimensions can be quickly compared with an existing breaker when checking physical fit.

Material Compliance and Certifications

• The NGB1B080B is HACR rated. No other certification or material-compliance information was provided for this part number, so do not assume additional listings or certifications.
• If your job has particular code, certification, or material requirements, check the markings on the breaker and the documentation for the equipment where it will be installed.

Where It Works Best

• The NGB1B080B makes the most sense when you’re maintaining a compatible NGB panelboard and need to match an existing 80 amp, 1-pole breaker. This is especially relevant with legacy electrical equipment, where matching the correct physical dimensions and electrical characteristics can be critical for a proper replacement.
• Before installation, compare more than just the breaker’s shape. Confirm the NGB1B080B part number, 80A rating, single-pole configuration, Type NGB designation, panelboard mounting, dimensions, terminal arrangement, voltage, and A.I.C. rating against the existing equipment.
• That simple check can save a lot of headaches. A breaker may look right at first glance but still have different electrical or mounting specifications. Confirm final compatibility and installation using the panelboard requirements and with a qualified electrical professional.
