NGB3B100B - 100 Amp Circuit Breaker

NGB3B100B - 100 Amp Circuit Breaker

When replacing a circuit breaker in an existing panelboard, attention should be paid to the small details. The NGB3B100B is a 100A, 3-pole molded case circuit breaker which belongs to the Type NGB family and is intended for use in panelboard-mounted installations. It has a rating of 25 kAIC at 480VAC and 100 kAIC at 240VAC and has dimensions of about 5.0 inches in height, 3.0 inches in width, and 3.06 inches in depth. Terminals on the load side are provided.

When carrying out maintenance on an existing or outdated electrical system, it is usually the case that the breaker you currently have should be matched. This involves going beyond just the 100-amp rating and examining the number of poles, the physical dimensions, the method of mounting, the voltage, the interrupting rating, and the terminal arrangement. The NGB3B100B provides a definite set of these characteristics for equipment that is designed to use this NGB configuration. It is also HACR rated and has a listed temperature rating of 40.25°C; furthermore, its molded case construction is capable of lasting provided that the breaker is properly applied, installed, and maintained.

Key Features and Benefits

• Breaker rated at 100 amperes and with three poles for use in compatible three-pole applications.
• The type NGB configuration is suitable for equipment designed around this breaker style.
• The rating is 25k AIC at 480VAC and 100k AIC at 240VAC.
• A panelboard mount that can be used in compatible panelboard installations.
• Load-side terminals included.
• HACR is rated for use in heating, air-conditioning, and refrigeration installations that are applicable.
• The dimensions are about 5.0" in height, 3.0" in width, and 3.06" in depth, which makes it easier to compare the physical size with that of the breaker being replaced.
• The case is designed to provide long-term service as long as it is correctly installed and kept in good condition.

Material Compliance and Certifications

• The breaker known as NGB3B100B has HACR approval. This is a key specification to take into account when considering the breaker for use in a heating, air-conditioning, or refrigeration application.
• The available specifications do not contain any other material-compliance certifications or material declarations. If a job has specific certification or material requirements, then those details should be verified with the relevant equipment documentation.

Where It Works Best

• The 100A, 3-pole Type NGB molded case circuit breaker known as the NGB3B100B is most appropriate for use in a current panelboard or in an older electrical installation which requires such a breaker having the same physical and electrical characteristics. Possible uses include commercial, industrial, institutional and HVAC electrical systems that are compatible.
• It's not enough just to locate a breaker that is marked "100A"; form, fit, and function are all important. You should compare the NGB3B100B part number together with the pole configuration, the mounting style, the dimensions, the voltage, the AIC rating, and the terminal requirements against the existing equipment. Carrying out that additional check will help you to decide if this breaker is suitable for the application.
