NEB1B110B - 110 Amp Circuit Breaker

NEB1B110B - 110 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NEB1B110B is a Type NEB molded case circuit breaker rated at 110 amps with a single-pole configuration. It's designed for panelboard mounting and measures 5.5 inches high, 1 inch wide, and 3 inches deep so that you can compare its physical size directly with the breaker already in place. Its interrupting ratings are 35 kA.I.C. at 277VAC and 85 kA.I.C. at 120VAC. The breaker is also HACR rated, has a 40.25°C temperature specification, and includes the load-side terminals. For electricians and maintenance teams working with older electrical equipment, the NEB1B110B is useful when the job calls for this particular Type NEB configuration rather than simply a breaker with the same amperage. Its molded-case construction is built to last in its intended application, while the clearly defined ratings make it easier to confirm it's the right match for the equipment you're servicing.

Key Features and Benefits

• 110-amp, 1-pole design for applications requiring this specific configuration.
• Type NEB molded case construction for compatible panelboard installations.
• 35k A.I.C. at 277VAC and 85k A.I.C. at 120VAC interrupting ratings.
• Panelboard-mount configuration for matching applicable existing equipment.
• HACR rated for compatible heating, air-conditioning, and refrigeration applications where this rating is required.
• Load-side terminals included with the breaker.
• Measures 5.5" H x 1.0" W x 3.0" D, giving you clear dimensions to check against the existing installation.
• Molded case construction that's built to last when correctly selected, installed, and maintained.

Material Compliance and Certifications

• The NEB1B110B is HACR rated, which matters when it's considered for a compatible heating, air-conditioning, or refrigeration application that calls for an HACR-rated breaker. The available specifications also list a temperature value of 40.25°C.
• The available specifications provide no other certifications or material-compliance declarations, so don't assume them. Check the breaker markings and the equipment and installation requirements when a particular certification, listing, or material standard is needed.

Where It Works Best

• The NEB1B110B makes the most sense in an existing electrical system that specifically calls for a Type NEB, 110 amp, 1-pole molded case circuit breaker with matching ratings and dimensions. It's particularly relevant for legacy panelboard maintenance, where replacing a breaker often comes down to matching the original form, fit, and electrical requirements as closely as possible.
• It may also be used in compatible HVAC applications where its HACR rating and other specifications meet the equipment requirements. Don't rely on amperage alone when checking fit. Compare the breaker type, number of poles, mounting arrangement, voltage, A.I.C. rating, dimensions, and other system requirements with the existing equipment before installation.
