NC361000 - 1000 Amp Circuit Breaker

NC361000 - 1000 Amp Circuit Breaker

When you replace a breaker in an existing electrical system, the small details matter as much as the amp rating. The NC361000 is a 1000A, 3-pole molded case circuit breaker with an I-Line plug-in design and thermal-magnetic trip operation. It measures 12.12 inches high, 14.98 inches wide, and 8.07 inches deep, giving you the key dimensions needed to check the fit against existing equipment.

On the electrical side, the NC361000 is rated 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC. Those ratings make it easier to determine whether the breaker matches the requirements of the system you're working on. For maintenance crews, electricians, and facility teams keeping legacy I-Line equipment in service, this breaker is best considered as a form, fit, and functional replacement where the NC type, 1000A rating, three-pole configuration, and plug-in connection are required. Its molded case construction is built to last when the breaker is correctly matched to the application and operated within its specified ratings.

Key Features and Benefits

• 1000A, 3-pole configuration for compatible electrical distribution applications.
• I-Line plug-in design for equipment that requires this connection style.
• Thermal-magnetic trip operation provides overload and short-circuit protection.
• 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC A.I.C. ratings provide clear specifications for matching the breaker to the system.
• 12.12" H × 14.98" W × 8.07" D dimensions make it easier to confirm physical fit before installation.
• The NC molded case design suits existing systems that require this breaker configuration.
• When properly selected, installed, and used within its specified electrical ratings, it is built to last.

Material Compliance and Certifications

• The available specifications did not include specific certification and material compliance information for the NC361000. Rather than assume UL, CSA, RoHS, REACH, or other designations, confirm any required compliance on the breaker's labeling and in supporting documentation.
• For applications with specific code, listing, or certification requirements, have the individual breaker and installation requirements reviewed before use.

Where It Works Best

• The NC361000 circuit breaker is intended for compatible I-Line electrical distribution equipment requiring a 1000A, 3-pole, plug-in thermal-magnetic molded case breaker. It's especially relevant when maintaining older commercial or industrial electrical systems where matching the existing breaker's physical configuration and electrical characteristics matters.
• If you're matching an existing NC361000, check more than the 1000-amp rating. Confirm the part number, number of poles, I-Line plug-in configuration, voltage, A.I.C. requirement, and physical dimensions. That straightforward comparison is the best way to determine whether the breaker has the correct form, fit, and function for the application.
