NGB2B015B - 15 Amp Circuit Breaker

NGB2B015B - 15 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NGB2B015B is a 15-amp, 2-pole Type NGB molded-case circuit breaker designed for compatible panelboard applications. It carries an interrupting rating of 25 kA.I.C. at 480VAC and 100 kA.I.C. at 240VAC, is HACR rated, and includes load-side terminals. The breaker measures 5.0 inches high, 2.0 inches wide, and 3.06 inches deep. Those dimensions, along with the mounting style and electrical ratings, are worth checking carefully when matching it to an existing installation. For maintenance and replacement work involving legacy electrical equipment, the NGB2B015B can provide the required form, fit, and function when these specifications match the original application. Its molded-case construction is built to last when used within its intended ratings and installed correctly.

Where It Works Best

• The NGB2B015B is a practical fit for maintenance and replacement work in compatible panelboards and legacy electrical systems that were designed around a Type NGB breaker. It's especially useful when the goal is simple: replace an existing breaker while keeping the original electrical and physical configuration intact.
• Before installation, take a minute to compare more than just the part number. Check the 15-amp rating, two-pole configuration, NGB type, A.I.C. and voltage ratings, panelboard mounting style, terminals, and physical dimensions against the existing equipment. These details help determine whether the NGB2B015B is the correct form, fit, and functional replacement for the job.
• For electrical professionals maintaining older equipment, straightforward compatibility matters most. When the application calls for these specifications, the NGB2B015B molded case circuit breaker provides the matching configuration needed to keep the existing system set up as intended.
