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 35 kAIC at 480VAC and 85 kAIC at 240VAC. The breaker measures about 5.5 inches high, 2 inches wide, and 3 inches deep, so you can compare these dimensions to the breaker already in your equipment. It is also HACR-rated, rated to 40.25°C, and includes load-side terminals.

Material Compliance and Certifications

The NEB2B080B is HACR rated, making it suitable for compatible heating, air-conditioning, and refrigeration applications where a 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.

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.
