NEB3B060B - 60Amp Circuit Breaker

NEB3B060B - 60Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the specifications right matters. The NEB3B060B is a 60-amp, 3-pole molded-case circuit breaker designed for panelboard mounting and applications that require the NEB type. It is rated 35 kA.I.C. at 480VAC and 85 kA.I.C. at 240VAC, with a 40°C rating and HACR rating. Load-side terminals are included. Measuring 5.5 inches high by 3 inches wide by 3 inches deep, the NEB3B060B can be a practical replacement when those dimensions, ratings, and mounting requirements match the existing equipment. For maintenance work on legacy electrical systems, the key is matching the breaker to the application rather than changing a setup that already calls for this configuration. It's a straightforward molded case breaker that's built to last and designed to do its job in compatible equipment.

Key Features and Benefits

• 60A, 3-pole design for compatible three-pole applications.
• NEB type for equipment designed around this breaker configuration.
• Panelboard mount for the intended installation style.
• Rated 35k A.I.C. at 480VAC and 85k A.I.C. at 240VAC.
• HACR rated for compatible applications where an HACR-rated breaker is specified.
• 40°C rating.
• Load-side terminals included.
• Measures 5.5" H x 3.0" W x 3.0" D, making it easier to compare the physical size with an existing breaker before replacement.
• A sensible option for maintaining legacy equipment when the part number and electrical specifications match.

Material Compliance and Certifications

• Available specifications identify the NEB3B060B as HACR-rated with a 40°C rating. Additional material-compliance or certification information has not been provided, so no other certifications are claimed here.
• As with any circuit breaker replacement, check the specifications against the equipment before installation. The part number is a good starting point, but amperage, pole count, voltage, interrupting rating, dimensions, mounting style, and terminal configuration should also match the application requirements.
  

Where It Works Best

• The NEB3B060B makes the most sense in existing panelboards and electrical distribution equipment designed to use the NEB breaker type. It's especially relevant for maintenance and replacement work on legacy systems where the goal is to keep the original form, fit, and function.
• You can also use it in compatible HACR applications when the equipment calls for a 60 amp, 3-pole breaker with these electrical ratings. Before putting it into service, compare the breaker you're replacing with the NEB3B060B specifications. Check the 60A rating, three poles, 35k A.I.C. at 480VAC / 85k A.I.C. at 240VAC rating, dimensions, panelboard mounting, and load-side terminal requirements. Those details tell you far more about suitability than marketing language ever could.
