NEB1B070B - 70 Amp Circuit Breaker

NEB1B070B - 70 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NEB1B070B is a 70-amp, 1-pole Type NEB molded-case circuit breaker made for compatible panelboard applications. It measures 5.5 inches high, 1.0 inch wide, and 3.0 inches deep, so start by checking those dimensions against your existing breaker. Electrically, the NEB1B070B is rated 35k AIC at 277VAC and 85k AIC at 120VAC. It's also HACR-rated for 40.25°C and comes with load-side terminals. For maintenance and replacement projects, this breaker is especially useful when you need to keep the existing Type NEB form, fit, and electrical configuration instead of changing the setup. Simply put, it's a purpose-built breaker designed to do its job and built to last when installed correctly and used within its specified ratings.

Key Features and Benefits

• 70-amp rating for compatible circuits requiring a 70A breaker.
• 1-pole design to match the configuration of applicable Type NEB equipment.
• 35k AIC at 277VAC and 85k AIC at 120VAC, providing clearly defined interrupting ratings to match your application.
• Panelboard mount configuration for compatible existing equipment.
• HACR-rated for applications that call for this rating, provided the remaining system requirements are met.
• Load-side terminals included, eliminating the guesswork about whether they're part of this breaker configuration.
• At 1.0 inch wide, the breaker maintains the physical footprint needed for compatible installations.
• Built to last when properly installed, maintained, and operated within its intended specifications.

Material Compliance and Certifications

• The NEB1B070B is HACR rated. No other material-compliance certifications were provided in the available specifications, so we don't make additional certification claims for this breaker.
• As with any replacement circuit breaker, don't rely on amperage alone when checking compatibility. The part number, number of poles, voltage and AIC ratings, dimensions, mounting arrangement, and terminal configuration should all match the requirements of the equipment where the breaker will be installed.

Where It Works Best

• The NEB1B070B makes the most sense when you're working on an existing panelboard or legacy electrical distribution system designed for a Type NEB breaker. It's a practical fit for maintenance and replacement jobs where you need to keep the original breaker configuration.
• If the equipment calls for a 70 amp, single-pole molded case circuit breaker with the NEB1B070B's dimensions and electrical ratings, this model gives you the form, fit, and function needed for that application. That's particularly helpful when maintaining older equipment where seemingly small differences in breaker dimensions or configuration can matter.
• Before installation, compare the existing equipment requirements with the NEB1B070B specifications above. A quick check of the 70A rating, single-pole design, AIC and voltage ratings, physical size, panelboard mounting, and terminals can help confirm you're using the correct breaker for the job.
