NCL36800 - 800 Amp Circuit Breaker

NCL36800 - 800 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the details right matters. The NCL36800 is an 80-amp, 3-pole molded case circuit breaker with thermal-magnetic protection and a cable-in/cable-out configuration. It's designed for compatible NCL applications where matching the original breaker's electrical ratings, physical dimensions, and connection style is important.

The NCL36800 has interrupting ratings of 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC. Measuring 19.5 inches high, 11.75 inches wide, and 5.75 inches deep, it gives electricians, maintenance teams, and facility managers the information they need to compare it with an existing breaker before installation.

Its thermal-magnetic trip design provides overload and short-circuit protection for its intended application. The molded-case construction keeps the breaker mechanism enclosed in a solid housing that's built to last in its intended electrical environment. For facilities maintaining legacy electrical equipment, the NCL36800 can provide the form, fit, and function required when its specifications match the original installation.

Key Features and Benefits

• 800 amp rating for compatible electrical distribution applications requiring an 800A breaker.
• 3-pole configuration for applicable three-phase systems.
• Thermal-magnetic trip provides protection against overload and short-circuit conditions.
• Cable-in/cable-out connections accommodate installations designed around this connection arrangement.
• Multiple interrupting ratings: 65 kA at 600VAC, 100 kA at 480VAC, and 125 kA at 240VAC.
• NCL type and defined dimensions help simplify comparison with an existing breaker when checking form and fit.
• Molded case construction provides a durable enclosure for the internal breaker mechanism.
• Built to last for its intended application without making unsupported claims about service life.

Material Compliance and Certifications

• The provided NCL36800 specifications do not include specific material-compliance declarations or certification details, so do not assume them. For applications requiring specific certifications or material-compliance standards, verify the markings and documentation on the individual breaker and confirm they meet the equipment and installation requirements.

Where It Works Best

• The NCL36800 800 amp circuit breaker is intended for compatible electrical distribution equipment requiring an NCL-type, 3-pole, thermal-magnetic molded case circuit breaker with cable-in/cable-out connections. It's particularly relevant for maintenance and replacement projects involving legacy equipment where matching the existing breaker's form, fit, and electrical characteristics is the priority.
• Before using the NCL36800 as a replacement, compare the 800A rating, three-pole configuration, system voltage, A.I.C. rating, physical dimensions, trip type, and connection arrangement with the existing breaker and equipment requirements. That simple specification-by-specification check helps determine whether the NCL36800 fits the intended installation.
