Material Compliance and Certifications

The NEB3B030B is HACR-rated and rated for 40 °C. The available specifications identify no other material-compliance certifications or agency listings, so do not assume them.

When using this breaker as a replacement, check more than the amperage alone. Confirm the part number, number of poles, voltage and interrupting ratings, dimensions, mounting arrangement, and the requirements of the panelboard or other equipment before installation.

Where It Works Best

The NEB3B030B circuit breaker is best suited to existing electrical systems and panelboards designed for the Type NEB configuration. It's a practical choice for maintenance and replacement work where matching the original breaker's specifications and physical fit is important.

You may also use this breaker in compatible heating, air-conditioning, and refrigeration applications that call for an HACR-rated breaker, provided the rest of the electrical specifications match the equipment.
