NEB3B025B - 25Amp Circuit Breaker

NEB3B025B - 25Amp Circuit Breaker

Need an NEB3B025B circuit breaker for an existing panelboard? This 25-amp, 3-pole molded-case circuit breaker is a Type NEB unit intended for compatible panelboard applications. It’s a practical fit for maintenance and replacement work where matching the breaker already used in the system is important. The NEB3B025B is rated 35kA at 480VAC and 85kA at 240VAC, with a 40°C rating and HACR rating. It measures approximately 5.5 inches high by 3 inches wide by 3 inches deep and includes load-side terminals. For older electrical equipment, details like frame type, amperage, pole count, mounting style, and interrupting rating can make all the difference when identifying the right replacement. If your application calls for the NEB3B025B and these specifications match your existing equipment, this breaker provides the familiar form, fit, and function needed to keep compatible electrical systems in service. Its molded case construction is built to last when used within the specified application and ratings.

Material Compliance and Certifications

• The NEB3B025B is HACR-rated, making it suitable for applicable heating, air-conditioning, and refrigeration circuits when the equipment and electrical system require this type of breaker.
• Because circuit breaker compatibility depends on more than amperage, check all relevant specifications before installation. Compare the part number, Type NEB configuration, three-pole design, voltage and A.I.C. ratings, mounting arrangement, dimensions, and terminal requirements with the existing equipment. Also confirm any additional certification or code requirements for the specific installation.
  

Where It Works Best

• The NEB3B025B makes the most sense in existing panelboards and legacy electrical systems that were designed for a 25A, 3-pole Type NEB molded case circuit breaker. In these applications, the goal isn’t to change the system—it’s to find a breaker with the correct physical configuration and electrical characteristics for the equipment already in place.
• That makes this model particularly relevant for electrical maintenance, equipment repair, and replacement projects that require an exact or specification-matched breaker. It can also serve qualifying HACR applications when all required ratings line up.
• Before putting the breaker into service, check it against the equipment you’re working on. A quick comparison of the NEB3B025B part number, 25-amp rating, three poles, A.I.C. ratings, NEB type, panelboard mounting, dimensions, and terminal configuration can help confirm that it matches the intended application.
