NGB3B030B - 30 Amp Circuit Breaker

NGB3B030B - 30 Amp Circuit Breaker

The NGB3B030B is a 30-amp, 3-pole molded-case circuit breaker for compatible Type NGB panelboard applications; it has a 25 kA interrupting rating at 480 VAC and 100 kA at 240 VAC, and load-side terminals.

When replacing a breaker in existing equipment, pay attention to the details. The NGB3B030B is 5.0 inches high and 3.0 inches wide, so confirm the available space and mounting requirements. This breaker is HACR-rated and has a 40.25°C rating.

When performing maintenance or replacement work, focus on the breaker's actual specifications rather than its appearance. Compare the NGB type, 30A rating, three-pole arrangement, AIC ratings, dimensions, and panelboard mounting requirements with those of the equipment you are working on. The molded case construction is designed to endure when the breaker is used in the application and within the rating conditions for which it was intended.

Material Compliance and Certifications

• The NGB3B030B has an HACR rating; the available specifications do not include other material compliance information, so do not assume additional certifications. For installation, confirm the equipment's breaker requirements, including amperage, number of poles, voltage, interrupting capacity, mounting style, dimensions, and breaker type.

Where It Works Best

• The Type NGB molded case circuit breaker known as the NGB3B030B is designed for use with compatible panelboards and for existing electrical systems that require a Type NGB molded case circuit breaker, and it is most appropriate in cases involving replacement and maintenance when it is important to match the original breaker in terms of its shape, fit, and electrical specifications.
• If you are replacing an existing unit, compare the NGB3B030B part number and specifications with those of the breaker being removed and the panelboard requirements; this simple check helps avoid problems that arise from choosing a breaker based solely on size or appearance.
