NC36900 - 900 Amp Circuit Breaker

NC36900 - 900 Amp Circuit Breaker

The NC36900 is a 900-amp, 3-pole molded-case circuit breaker with an I-Line plug-in design and thermal-magnetic trip. It’s intended for existing electrical equipment that requires this specific NC breaker configuration. For maintenance or replacement work, the important thing is getting the details right—not just the amperage. This breaker measures 12.12 inches high, 14.98 inches wide, and 8.07 inches deep, so check those dimensions along with the mounting style and electrical ratings. Interrupting capacity is 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC. If you’re replacing an existing breaker, compare the NC36900 part number, 900A rating, three-pole configuration, I-Line connection, dimensions, and A.I.C. ratings with the breaker and equipment already in place. Its molded case construction is built to last when used in the correct application and properly maintained.

Material Compliance and Certifications

• The available product specifications did not include specific certifications, listings, or material-compliance information. Check the markings on the individual breaker and the applicable product documentation when you must confirm a particular certification or compliance requirement.

Where It Works Best

• The NC36900 circuit breaker is intended for existing electrical distribution systems that call for an NC-type, 900 amp, 3-pole I-Line plug-in breaker with matching electrical and physical characteristics. That makes it particularly relevant for maintenance and replacement work involving compatible legacy equipment.
• Before installation, check more than the part number. Confirm the amperage, poles, voltage, interrupting rating, dimensions, connection style, and equipment requirements. Qualified electrical personnel should verify final compatibility and installation.
