NEB1B015B - 15Amp Circuit Breaker

NEB1B015B - 15 Amp Circuit Breaker

Finding the right circuit breaker for an existing panel often comes down to the details. The NEB1B015B is a 15-amp, 1-pole Type NEB molded-case circuit breaker made for compatible panelboard applications. It has an interrupting rating of 35k AIC at 277VAC and 85k AIC at 120VAC, along with a 40°C rating and HACR rating. The breaker measures about 5.5 inches high, 1 inch wide, and 3 inches deep, so it can be a good fit for maintenance and replacement work where the original breaker's size and mounting configuration must match closely. Load-side terminals are included. For older and legacy electrical systems, that combination of physical size, amperage, pole configuration, and interrupting capacity matters. Rather than choosing a breaker based on amperage alone, compare the NEB1B015B specifications with your panel and existing equipment requirements. When those specifications match, this breaker provides a practical way to maintain the intended form, fit, and function of the installation. It's built to last and designed to perform its intended job within the stated electrical ratings.

Where It Works Best

• The NEB1B015B is best suited to compatible panelboards and legacy electrical systems that call for this part number or the same Type NEB configuration and ratings. It can be especially useful during maintenance or repair work where keeping the original breaker dimensions and electrical characteristics is important.
  
• Compatibility should always be checked carefully. Start with the 15 amp rating and 1-pole configuration, then confirm the voltage and AIC requirements, physical dimensions, panelboard mounting style, and terminal arrangement. If those details match the existing equipment requirements, the NEB1B015B provides the right form, fit, and function for the application.
