NEB2B080B - 80 Amp Circuit Breaker

NEB2B080B - 80 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NEB2B080B is a Type NEB molded-case circuit breaker with an 80-amp rating and a 2-pole configuration. It's designed for panelboard mounting and is rated 35k AIC at 480VAC and 85k AIC at 240VAC. The breaker measures approximately 5.5 inches high, 2 inches wide, and 3 inches deep, giving you another set of details to check against the breaker already in your equipment. It is also HACR-rated, has a 40.25°C temperature rating, and comes with load-side terminals. For electricians and maintenance teams working with compatible legacy equipment, the NEB2B080B offers the specific form, fit, and electrical characteristics needed for applications designed around this breaker. It's a straightforward replacement option when the part number, ratings, mounting style, dimensions, and other application requirements line up. These breakers are built to last when correctly installed and used within their specified ratings.

Material Compliance and Certifications

• The NEB2B080B is HACR rated, making it suitable for compatible heating, air-conditioning, and refrigeration applications where an HACR-rated breaker is specified. Its stated electrical ratings include 35k AIC at 480VAC and 85k AIC at 240VAC, along with a 40.25°C temperature rating.
• No other material-compliance certifications or environmental declarations were provided in the available specifications. When a project requires a specific listing or certification, verify it against the equipment documentation before installation.

Where It Works Best

• The NEB2B080B 80 amp circuit breaker is intended for compatible panelboards and legacy electrical systems that call for a Type NEB, 2-pole molded case circuit breaker with these specific ratings and dimensions. Typical applications may include commercial and industrial electrical systems, facility maintenance, and compatible HVAC installations.
• For replacement work, start with the part number—but don't stop there. Check the 80 amp rating, two-pole configuration, AIC and voltage ratings, panelboard mounting style, dimensions, and terminal arrangement against the existing breaker and panel requirements. A breaker can look similar and still not be right for the equipment.
• When those specifications match, the NEB2B080B provides the form, fit, and function needed for the intended application. Qualified electrical personnel should confirm final compatibility and installation in accordance with applicable codes and equipment requirements.
