NC36800 - 800 Amp Circuit Breaker

NC36800 - 800 Amp Circuit Breaker

The NC36800 is an 800-amp, 3-pole molded case circuit breaker with an I-Line plug-in configuration and thermal-magnetic operation. If you're working with existing equipment that calls for a Type NC breaker, the key is getting the details right—and this unit has clearly defined ratings to help you match it. It is rated 65 kA at 600 VAC, 100 kA at 480 VAC, and 125 kA at 240 VAC. The breaker measures 12.12 inches high, 14.98 inches wide, and 8.07 inches deep. That combination of part number, physical size, amperage, pole count, connection style, and interrupting ratings makes the NC36800 particularly useful when maintaining an existing I-Line installation where form, fit, and function matter. It's a straightforward molded-case breaker built to last and designed to do the job it was made for.

Material Compliance and Certifications

• The available specifications for the NC36800 do not include specific material compliance information or certification details. Rather than assume approvals or certifications, verify them through the breaker markings and applicable manufacturer documentation when required for a particular installation.

Where It Works Best

• The NC36800 makes sense when you're maintaining an existing electrical system that was designed for a Type NC, 800A, 3-pole I-Line plug-in breaker. In these situations, finding the right replacement is less about extra features and more about matching what the equipment actually requires.
• Before using an NC36800 as a replacement, compare the part number, amperage, number of poles, I-Line connection, physical dimensions, voltage, and A.I.C. rating with the existing breaker and equipment requirements. These details determine whether the breaker fits the application. Qualified electrical personnel should confirm final compatibility and installation.
