NCL361000 - 1000 Amp Circuit Breaker

NCL361000 - 1000 Amp Circuit Breaker

Need an NCL361000 circuit breaker for an existing electrical system? Getting the details right matters, especially with legacy equipment where the breaker's size, configuration, amperage, and interrupting rating must match the application. The NCL361000 is a 1000-amp, 3-pole molded-case circuit breaker with a thermal-magnetic trip mechanism and a cable-in/cable-out configuration. It carries interrupting ratings of 65kA at 600VAC, 100kA at 480VAC, and 125kA at 240VAC. Measuring 12.12 inches high, 14.98 inches wide, and 8.07 inches deep, this Type NCL breaker is a practical choice when maintaining compatible electrical distribution equipment and preserving the required form, fit, and function. Simply put, when your existing equipment calls for an NCL361000—or its specifications are confirmed as compatible—this breaker provides the electrical ratings and physical configuration needed to keep that system in service. It's built to last in its intended application, without unnecessary bells and whistles or exaggerated claims.

Key Features and Benefits

• 1000A, 3-pole configuration for compatible three-phase electrical applications.
• Thermal-magnetic trip mechanism provides the specified circuit protection characteristics of the NCL361000.
• 65kA interrupting rating at 600VAC for applications operating at this voltage and available fault-current level.
• 100kA at 480VAC and 125kA at 240VAC, making it easy to identify the appropriate A.I.C. rating for the system voltage.
• Cable-in/cable-out configuration helps match installations designed around this connection arrangement.
• Type NCL molded case design supports straightforward identification when maintaining compatible legacy equipment.
• Known physical dimensions make it easier to check available space and fit before installation.
• When properly selected, installed, and operated within its specified electrical ratings, it is built to last.

Material Compliance and Certifications

• Specific material compliance and certification information is not included in the available NCL361000 specifications. Therefore, do not assume UL, CSA, RoHS, or other certification and compliance status. When an application requires a specific listing or certification, confirm it using the breaker labeling and applicable authoritative product documentation.

Where It Works Best

• The NCL361000 1000A molded case circuit breaker makes the most sense in compatible legacy electrical distribution systems where matching the existing equipment is the priority. It is especially relevant for maintenance and replacement applications requiring a 1000A, 3-pole, thermal-magnetic breaker with the NCL361000's cable-in/cable-out arrangement, physical footprint, voltage, and interrupting ratings.
• For maintenance teams, electricians, facility managers, and industrial operators, that means less guesswork when identifying a form, fit, and functional replacement. The important thing is compatibility: confirm the part number, 1000A rating, three-pole configuration, dimensions, system voltage, A.I.C. requirement, and connection arrangement against the existing equipment before installation.
