NGB1B060B - 60 Amp Circuit Breaker

NGB1B060B - 60 Amp Circuit Breaker

When you're maintaining an existing electrical system, getting the breaker details right matters. The NGB1B060B is a 60-amp, 1-pole Type NGB molded-case circuit breaker for compatible panelboard applications. It has an interrupting rating of 25k AIC at 277VAC and 100k AIC at 120VAC, along with an HACR rating and a temperature specification of 40.25°C. The breaker measures 5.0 inches high, 1.0 inch wide, and 3.06 inches deep, so you can check those dimensions against the existing equipment when confirming fit. Load-side terminals are included. This breaker is well suited to maintenance and replacement work where the existing panelboard calls for the same Type NGB configuration and electrical ratings. Its molded case construction is built to last when properly installed and used within its stated ratings. As with any replacement circuit breaker, matching the 60A rating alone isn't enough—the part number, poles, voltage, AIC rating, mounting style, dimensions, and terminal arrangement should all match the equipment requirements.

Key Features and Benefits

• 60A, single-pole design for applications requiring this specific configuration.
• Type NGB molded case construction for use with compatible equipment.
• Rated 25k AIC at 277VAC and 100k AIC at 120VAC.
• Panelboard mount configuration.
• HACR rated for applications where this designation is required.
• Load-side terminals included with the breaker.
• Measures just 1 inch wide, an important detail when checking physical fit in an existing panelboard.
• A practical option for maintenance and functional replacement in compatible legacy electrical systems.
• Built to last when installed correctly and operated within the specified electrical limits.

Material Compliance and Certifications

• The NGB1B060B is HACR rated. Based on the available product information, its specified electrical characteristics are 60A, 25k AIC at 277VAC, and 100k AIC at 120VAC.
• No other material-compliance declarations or certifications are identified in the supplied specifications. If a project has particular code, certification, listing, or material-compliance requirements, check the breaker markings and applicable equipment documentation before installation.

Where It Works Best

• The NGB1B060B makes the most sense when you're working on an existing panelboard that requires a Type NGB, 1-pole, 60 amp molded case circuit breaker with these particular electrical and physical characteristics. That makes it especially useful for maintenance and replacement situations involving compatible legacy electrical equipment.
• The key is matching what the system actually requires. Before using the NGB1B060B as a replacement, compare the part number, 60A amperage, single-pole configuration, AIC and voltage ratings, physical dimensions, panelboard mounting, and load-side terminal arrangement with the existing breaker and equipment documentation. A breaker that looks similar isn't necessarily a functional match.
