NGB1B035B - 35 Amp Circuit Breaker

NGB1B035B - 35 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the small details can make all the difference. The NGB1B035B is a 35-amp, 1-pole molded-case circuit breaker in the NGB series, designed for panelboard mounting. It has an interrupting rating of 25k AIC at 277VAC and 100k AIC at 120VAC and measures 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 comes with load-side terminals. For facilities maintaining existing or legacy equipment, the NGB1B035B can be a practical replacement when these specifications match the breaker and panel requirements already in place. Rather than substituting a breaker based on amperage alone, check the full set of ratings, dimensions, mounting style, and pole configuration. When the application calls for this specific NGB setup, the NGB1B035B gives you the form, fit, and function needed to keep compatible equipment in service. It's a straightforward breaker that's built to last when properly selected and used within its stated ratings.

Key Features and Benefits

• 35-amp rating for applications that specify a 35A breaker.
• Single-pole design for compatible 1-pole circuits and equipment.
• NGB molded case construction with a panelboard-mount configuration.
• Rated 25k AIC at 277VAC and 100k AIC at 120VAC.
• HACR rated for applications that require an HACR-rated breaker.
• Load-side terminals are included, so the breaker retains this required configuration.
• At 5.0" H x 1.0" W x 3.06" D, its dimensions can be checked directly against the breaker being replaced.
• Designed for lasting service when correctly installed and operated within its specified ratings.

Material Compliance and Certifications

• The NGB1B035B is HACR rated and has a stated temperature rating of 40.25°C. Its listed interrupting ratings are 25k AIC at 277VAC and 100k AIC at 120VAC.
• The available specifications provide no additional material-compliance information or agency certifications, so assume none. If your installation has specific code, certification, or material requirements, verify those requirements before installing the breaker.

Where It Works Best

• The NGB1B035B is best suited to compatible panelboards and legacy electrical equipment that require this particular NGB breaker configuration. It's especially relevant for repair and maintenance work where the goal is to keep the existing form, fit, and electrical characteristics.
• One thing worth checking carefully: 35 amps alone doesn't determine compatibility. Compare the existing breaker with the NGB1B035B's 1-pole configuration, voltage and AIC ratings, panelboard mounting, physical dimensions, and terminal requirements. Those details help determine whether this is the correct functional replacement for the application.
