NCL36700 - 700 Amp Circuit Breaker

NCL36700 - 700 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the details right matters. The NCL36700 is a 700A, 3-pole molded case circuit breaker with a thermal-magnetic trip and cable-in/cable-out configuration. It carries interrupting ratings of 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC. For replacement work, its dimensions are 12.12 inches high, 14.98 inches wide, and 8.07 inches deep. Those specifications give electricians, maintenance teams, and facility personnel a straightforward way to compare the NCL36700 with the breaker and equipment already in place. For legacy electrical systems that call for this Type NCL configuration, it can provide the form, fit, and function needed to keep compatible equipment in service. It's a straightforward circuit protection component that's built to last in the application it was designed for.

Key Features and Benefits

• 700-amp rating for equipment designed around this amperage requirement.
• Three-pole design for compatible three-pole electrical applications.
• Thermal-magnetic trip provides overcurrent protection.
• Cable-in/cable-out configuration for systems requiring this connection arrangement.
• Multiple interrupting ratings: 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC.
• Type NCL construction helps simplify identification when matching an existing breaker.
• Known physical dimensions make it easier to check available space and equipment fit before installation.
• Built to last for its intended electrical distribution application.

Material Compliance and Certifications

• Specific material compliance information and certification listings were not provided with the available NCL36700 specifications. Because these details matter when matching electrical equipment, verify applicable certifications or compliance requirements against the breaker label and supporting equipment documentation rather than assume them.

Where It Works Best

• The NCL36700 circuit breaker is best suited to existing and legacy electrical equipment that requires a 700A, 3-pole Type NCL molded case breaker with a thermal-magnetic trip and cable-in/cable-out connections. It can be especially useful in maintenance and replacement situations where keeping the existing system configuration is important.
• Before using the NCL36700 as a replacement, compare the full specifications—not simply the part number. Amperage, voltage, interrupting rating, pole count, dimensions, connection style, and equipment compatibility should match the installation requirements. Qualified electrical personnel should determine final suitability and installation using the applicable equipment documentation and electrical codes.
