NGB1B110B - 110 Amp Circuit Breaker

NGB1B110B - 110 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the small details matter. The NGB1B110B is a Type NGB molded case circuit breaker with a 110-amp, 1-pole configuration and a panelboard-mount design. It is rated 25k AIC at 277VAC and 100k AIC at 120VAC and measures approximately 5.0 inches high, 1.0 inch wide, and 3.06 inches deep. The breaker is also HACR rated, has a 40.25°C rating, and includes load-side terminals. For electricians, maintenance departments, and facility teams working with compatible legacy equipment, the NGB1B110B can provide the form, fit, and function needed to keep the existing system configuration intact. Rather than changing equipment unnecessarily, you can match the breaker by part number, amperage, pole count, dimensions, mounting style, and electrical ratings. It's a straightforward solution for applications that specifically call for this NGB configuration, and these breakers are built to last when properly selected and used within their stated ratings.

Key Features and Benefits

• 110A, 1-pole configuration for compatible electrical applications requiring these specific ratings.
• Type NGB molded case design helps match existing equipment that calls for an NGB breaker.
• Rated 25k AIC at 277VAC and 100k AIC at 120VAC.
• Panelboard mount for compatible panelboard installations.
• Measures approximately 5.0" H x 1.0" W x 3.06" D, making it easy to compare the physical size with an existing breaker.
• HACR-rated for applicable heating, air-conditioning, and refrigeration circuit applications.
• Includes load-side terminals in the specified configuration.
• Well suited to maintenance and replacement work in compatible legacy electrical systems where keeping the original breaker configuration is important.

Material Compliance and Certifications

• The NGB1B110B is HACR rated and carries a specified 40.25°C rating. Check these details, along with the breaker's other electrical specifications, when determining whether it meets the requirements of an existing application.
• No other material-compliance certifications or environmental declarations were provided in the available specifications, so they aren't assumed here. For installations with specific certification or compliance requirements, confirm those requirements against the applicable equipment documentation.
  

Where It Works Best

• The NGB1B110B is a good fit for compatible panelboards and legacy electrical distribution equipment that require a 110A, single-pole Type NGB molded case circuit breaker. It's especially relevant when you're repairing or maintaining an existing system and need a breaker that matches the original configuration.
• Before replacing an existing breaker, compare more than just the amperage. Check the part number, breaker type, number of poles, AIC and voltage ratings, physical dimensions, mounting configuration, and terminal requirements. Matching those details is important when determining whether the NGB1B110B provides the correct form, fit, and function for the application.
