NGB3B080B - 80 Amp Circuit Breaker

NGB3B080B - 80 Amp Circuit Breaker

If you're hunting around for an NGB3B080B, it's likely that you already possess some panel or piece of equipment that requires this specific breaker. It is an 80 amp, 3-pole Type NGB molded case circuit breaker with a panelboard-mount configuration. The 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. The load-side terminals are provided.

The breaker has dimensions of 5.0 inches in height, 3.0 inches in width, and 3.06 inches in depth. It's important to compare these figures with the breaker you plan to remove, especially in the case of an older panel where achieving the correct physical fit is just as crucial as ensuring that the amp rating matches. You should also check the number of poles, the mounting configuration, the voltage, and the AIC ratings. If the existing equipment identifies it as the NGB3B080B and all of these details agree, then you have both the right shape, the correct fit, and the proper function as required by the original installation. This breaker is designed to last, provided it is installed and used within the ratings specified.

• Before carrying out the installation, verify the installation's required code, listing, certification, or compliance with materials against the breaker's documentation. The present text makes no further claims regarding certification than those given for this breaker.

Where It Works Best

• This breaker should be used in compatible panelboards and with existing electrical equipment which is designed for the Type NGB configuration. In the majority of cases when carrying out a replacement, the aim is not to alter what is already in place but rather to locate the breaker that matches the type the equipment was designed to use.
• Begin by noting the part number, NGB3B080B, and then compare the basic specifications of the new breaker with those of the existing one—looking at 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. Never base your decision solely on the amperage.
