NJL631200 - 200Amp Circuit Breaker

NJL631200 - 200Amp Circuit Breaker

The NJL631200 is a 200A, 3-pole thermal-magnetic molded-case circuit breaker for compatible electrical equipment using the NJL bolt-on configuration. If you're replacing an existing breaker, the details are what matter. This model measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep, and includes load-side lug terminals. It carries an interrupting rating of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, with a 40°C rating. The NJL631200 is also known as NJL632200, so either number may appear in equipment records, maintenance documentation, or on an existing breaker. For older electrical systems that were designed around this NJL configuration, it provides the familiar form, fit, and function needed for a properly matched replacement. Its molded case construction is built to last when the breaker is correctly applied, installed, and maintained.

Key Features and Benefits

• 200A rating for applications designed around this amperage.
• 3-pole configuration for compatible three-phase electrical systems.
• Thermal magnetic trip design provides the circuit protection characteristics specified for this breaker.
• Bolt-on mounting fits equipment designed for the corresponding NJL breaker configuration.
• Multiple A.I.C. ratings: 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC.
• Load-side lug terminals are included, giving you the specified terminal arrangement for this model.
• 40°C rating for applications that require this temperature rating.
• Also identified as NJL632200, which can help when cross-checking existing breaker or equipment documentation.
• Well suited for legacy equipment maintenance and replacement where the original electrical and physical specifications must be maintained.

Material Compliance and Certifications

• The available specifications for the NJL631200 did not include specific material compliance information, agency certifications, listings, or certification numbers. Rather than assume a certification applies, check the breaker markings and applicable technical documentation when a particular listing or material standard is required for the installation.

Where It Works Best

• The NJL631200 200A circuit breaker makes the most sense in maintenance and replacement situations where the existing electrical equipment was designed for this particular NJL breaker configuration. That can include compatible commercial and industrial electrical distribution equipment, especially legacy systems where keeping the correct breaker dimensions, mounting arrangement, amperage, pole count, and interrupting rating is important.
• One thing worth checking before replacing an existing breaker: 200 amps and three poles aren't the whole story. Also confirm the mounting style, physical dimensions, system voltage, required A.I.C. rating, trip type, and terminal configuration. For the NJL631200, those details include bolt-on mounting, thermal magnetic operation, a 10.13 x 8.25 x 3.88-inch enclosure size, and the specified interrupting ratings at 240VAC, 480VAC, and 600VAC.
• When those specifications match the existing equipment requirements, the NJL631200 provides a straightforward way to maintain the system's intended form, fit, and function. A qualified electrical professional should always confirm compatibility and installation, and complete the work according to applicable electrical codes and equipment requirements.
