NGB3B110B - 110 Amp Circuit Breaker

NGB3B110B - 110 Amp Circuit Breaker

It's important to get the details right if you're replacing a breaker in an existing panelboard. The NGB3B110B is a Type NGB molded case circuit breaker with a rating of 110 amps and having three poles. It is intended for use in panelboard installations and has interrupting ratings of 25 kA at 480 VAC and 100 kA at 240 VAC. The breaker is 5.0 inches high, 3.0 inches wide, and 3.06 inches deep, so its dimensions can be verified against the existing equipment prior to installation. It is also HACR rated, has a 40.25°C rating, and includes load-side terminals. When carrying out maintenance or replacement in compatible legacy electrical equipment, the NGB3B110B provides a definite combination of amperage, number of poles, dimensions, and interrupting capacity. The molded case construction is built to endure as long as it is properly installed and used within the ratings stated.

Key Features and Benefits

• The rating is 110 amps for use in cases where this particular current rating is required.
• Designed with three poles to ensure compatibility with three-pole electrical systems.
• The Type NGB configuration enables the breaker to be matched with equipment that is designed for this type of breaker.
• The interrupting capacity is 25kA at 480VAC and 100kA at 240VAC.
• A panelboard mount that can be used in compatible panelboard installations.
• The device can be used in cases where an HACR-rated breaker is required, and the other specifications are compatible.
• The load-side terminals are included in the breaker configuration.
• The small size of the device makes it simpler to check whether it fits physically in the breaker it is replacing.
• The molded case construction is designed so that it can provide reliable service within the operating conditions specified for the breaker.

Material Compliance and Certifications

• The NGB3B110B has a HACR rating; no further material-compliance certificates are listed in the available specifications, and so no other certifications should be assumed. If the installation involves specific code, certification, or material-compliance requirements, it is necessary to refer to the relevant equipment documentation prior to carrying out the installation.

Where It Works Best

• The NGB3B110B breaker is most appropriate in the case where you have an existing Type NGB panelboard or a compatible old electrical system and need a breaker that matches the original in terms of its shape, size, and function. Instead of selecting a breaker on the basis of its amperage only, you should examine the entire application, since the number of poles, the interrupting capacity, the voltage, the physical dimensions, the method of mounting, and the terminal arrangement are all important factors.
• The NGB3B110B could be the right choice when an application calls for a 110A, 3-pole Type NGB molded case circuit breaker with those ratings and dimensions, especially in cases involving electrical maintenance, equipment repair, and replacement work where the aim is to keep the existing system in its original configuration.
• Prior to installing the component, the full specifications of the NGB3B110B should be checked against those of the panelboard and the breaker that is to be replaced. The installation must be carried out by qualified electrical personnel and in compliance with the relevant electrical codes and the equipment requirements.
