NGB3B090B - 90 Amp Circuit Breaker

NGB3B090B - 90 Amp Circuit Breaker

The NGB3B090B is a 90-amp, 3-pole molded-case circuit breaker suitable for compatible Type NGB panelboards. When replacing an existing breaker, it is important to take the details into account. This breaker has an interrupting rating of 25 kA at 480 VAC and 100 kA at 240 VAC, is HACR rated, and includes load-side terminals. Its physical dimensions are 5.0 inches high, 3.0 inches wide, and 3.06 inches deep. It is a suitable choice when maintaining compatible legacy electrical equipment since the NGB3B090B part number, mounting arrangement, dimensions, and electrical ratings correspond to those required. The molded case design is built to withstand proper operating conditions. Before putting it into service, you should compare the full breaker specifications with those of the panelboard and the existing equipment. A 90 amp rating alone is not enough to confirm a circuit breaker is the right one.

Key Features and Benefits

• For systems that need these particular characteristics, a 90-amp, 3-pole setup is provided.
• The Type NGB molded case is suitable for use with panelboard applications.
• It has a rating of 25kA at 480VAC and 100kA at 240VAC.
• HACR is rated for use in cases where an HACR designation is required.
• Panelboard mount configuration.
• Load-side terminals are included.
• The dimensions of the product, 5.0" H x 3.0" W x 3.06" D, make it simpler to verify that it will fit physically.

Material Compliance and Certifications

• The NGB3B090B has an HACR rating, and there are no further material-compliance certificates or environmental declarations mentioned in the specified documents.
• If the application has specific requirements relating to code, certification, or materials, it is necessary to check those requirements separately prior to carrying out the installation.

Where It Works Best

• It is designed to fit compatible Type NGB panelboards as well as older electrical equipment that requires its specific shape, size, and rating. It is particularly appropriate in cases where you are carrying out maintenance on an existing system and need to use a 90A, 3-pole panelboard-mounted breaker rather than altering the equipment configuration.
• When you are checking compatibility, begin with the NGB3B090B part number, but don't stop with that. You should also compare the pole count, the amperage, the physical size, the mounting arrangement, the voltage, the interrupting rating, and the terminal requirements with those given in the existing breaker and equipment documentation.
• Before installation, check electrical compatibility. Qualified electrical personnel should carry out the installation in accordance with the relevant electrical codes and the equipment requirements.
