NGB2B030B - 30 Amp Circuit Breaker

NGB2B030B - 30 Amp Circuit Breaker

Need an NGB2B030B for an existing panelboard? This 30-amp, 2-pole molded-case circuit breaker is an NGB Type breaker intended for compatible panelboard applications. It measures 5.0" high x 2.0" wide x 3.06" deep and has an interrupting rating of 25kA at 480VAC and 100kA at 240VAC. The breaker is also HACR rated, has a 40.25°C temperature rating, and comes with load-side terminals. Those details matter most when you're replacing a breaker in an existing or legacy electrical system, where the correct form, fit, and electrical ratings are critical. For maintenance work, start by comparing the NGB2B030B part number and specifications with the installed breaker. It's a straightforward, built-to-last solution for applications designed around this particular NGB configuration.

Material Compliance and Certifications

• Available specifications identify the NGB2B030B as HACR rated. No other material-compliance certifications or listings are specified in the information provided for this breaker.
• If a particular certification or listing is required for the job, check the markings on the actual breaker and the panelboard or equipment documentation before installation. This is particularly important with older electrical systems, where matching the correct breaker type and ratings is essential.
  

Where It Works Best

• The NGB2B030B makes the most sense when maintaining a compatible panelboard or legacy electrical system that was designed for an NGB Type molded case circuit breaker with these specifications. Rather than changing the electrical system around the breaker, focus on matching the existing application as closely as possible.
• Before replacing an existing breaker, compare more than the catalog number. Also check the 30 amp rating, 2-pole configuration, voltage, A.I.C. rating, dimensions, mounting style, and terminal arrangement. Two breakers can look similar and still have important differences.
• For that reason, use the NGB2B030B only when its specifications match the requirements of the existing equipment. A qualified electrical professional should verify compatibility and handle installation in accordance with applicable electrical codes and equipment requirements.
