NGB3B070B - 70 Amp Circuit Breaker

NGB3B070B - 70 Amp Circuit Breaker

If you're looking for an NGB3B080B, it's probably the case that you already have some panel or other piece of equipment that needs this particular breaker. It is an 80-amp, 3-pole Type NGB molded-case circuit breaker with a panelboard-mount arrangement. Its interrupting capacities are 25 kAIC at 480 VAC and 100 kAIC at 240 VAC; it is also HACR rated and has a temperature rating of 40.25°C. Terminals are provided on the load side.

The breaker measures 5.0 inches high, 3.0 inches wide, and 3.06 inches deep. It is essential to compare these dimensions with the breaker you intend to remove, particularly when dealing with an older panel, since getting the correct physical fit is just as important as making sure the amp rating is the right one. You must also verify the number of poles, the mounting arrangement, the voltage, and the AIC ratings. Only when the existing equipment labels it as NGB3B080B and all of these details agree can you be sure that you have the right shape, the correct fit, and the proper function as required by the original installation. This breaker is one that is designed to last if it is installed and used within the ratings specified.

• Prior to carrying out the installation, you should check the code, listing, certification, or compliance requirements for the installation against the documentation provided with the breaker. This text makes no additional claims concerning certification beyond those already made for this breaker.

Where It Works Best

• This breaker must be used in panelboards that are compatible with it and with the existing electrical equipment which is designed for the Type NGB configuration; in most instances, when carrying out a replacement, the objective is not to change what is already there but merely to find the breaker which matches the type that the equipment was designed to use.
• Start by recording the part number, NGB3B080B, and then compare the basic specifications of the new breaker with those of the present one by referring to the amperage, the number of poles, the panelboard mounting type, the physical size, the voltage, the AIC rating, the temperature rating, and the terminal arrangement. Do not base your decision entirely on the amperage.
