NEB2B030B - 30 Amp Circuit Breaker

NEB2B030B - 30 Amp Circuit Breaker

Need an NEB2B030B for an existing panelboard? This Type NEB molded-case circuit breaker is a 30-amp, 2-pole unit made for compatible panelboard-mounted applications. It measures 5.5 inches high, 2 inches wide, and 3 inches deep, so it's easy to compare the physical footprint with the breaker you're replacing. Electrical ratings are 35k AIC at 480VAC and 85k AIC at 240VAC. The breaker is also HACR-rated, carries a 40.25°C rating, and includes load-side terminals. For maintenance work on legacy electrical equipment, those details matter. A breaker may look similar at first glance, but the part number, mounting arrangement, dimensions, poles, amperage, and interrupting rating must all suit the application. If your equipment specifies the NEB2B030B and these ratings match your requirements, this breaker gives you the form, fit, and function needed to keep the existing system configuration intact. It's a straightforward, built-to-last component designed to do the job.

Material Compliance and Certifications

• The NEB2B030B is HACR-rated. The supplied specifications identify no other certifications or material-compliance declarations, so none are assumed here.
• As with any circuit breaker replacement, don't determine compatibility by appearance alone. Check the part number and electrical ratings along with the mounting style, dimensions, pole configuration, and terminals. Follow the equipment requirements and applicable electrical codes for installation.

Where It Works Best

• The NEB2B030B makes the most sense in compatible legacy panelboards and electrical distribution equipment that call for a Type NEB breaker with these specifications. It's especially relevant when the goal is simple: replace a matching breaker while keeping the original equipment configuration in service.
• Before installation, compare the existing breaker with the NEB2B030B part number, 30 amp rating, 2-pole configuration, panelboard mounting, dimensions, terminals, and applicable AIC and voltage ratings. Matching those details helps ensure you select the correct form, fit, and function for the equipment—without unnecessary changes to the existing system.
