NDC3800T36W - 800 Amp Circuit Breaker

NDC3800T36W - 800 Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, the details matter. The NDC3800T36W is an 800-amp, 3-pole N-Frame molded-case circuit breaker for systems that require this specific NDC configuration. It has an interrupting rating of 65 kA at 600 VAC, 100 kA at 480 VAC, and 200 kA at 240 VAC. The breaker uses a thermal-magnetic electronic design with non-interchangeable trip units and includes independently adjustable short-time pickup and delay, plus ground-fault protection. It's also HACR-rated. At 16 inches high, 8.25 inches wide, and 5.5 inches deep, the NDC3800T36W fits well for maintenance and replacement work where the existing equipment must stay in its original configuration. One detail worth checking before installation: the catalog number does not include a rating plug or lug terminals. Those components must match the equipment's requirements. For facilities keeping older electrical systems in service, this breaker provides the form, fit, ratings, and functions required for compatible NDC N-Frame applications. It's a straightforward, built-to-last solution when your system requires it.

Key Features and Benefits

• 800-amp, 3-pole design for compatible NDC N-Frame applications.

Material Compliance and Certifications

• The NDC3800T36W is HACR rated. That makes it applicable to compatible heating, air-conditioning, and refrigeration equipment when an HACR-rated breaker is specified.
• No other material-compliance certifications were included in the supplied product information. If the installation has specific certification, code, or material requirements, confirm them for the application before installing the breaker.

Where It Works Best

• The NDC3800T36W makes the most sense when you're working on an existing electrical system that was designed for a compatible NDC N-Frame breaker. Instead of changing the equipment configuration, maintenance teams can match the breaker's physical size, 800A rating, three-pole arrangement, interrupting capacity, and protection functions to existing requirements.
• Typical applications can include compatible commercial, industrial, and HVAC electrical equipment, particularly where the original system calls for this specific breaker configuration.
• As with any replacement circuit breaker, don't match on amperage alone. Check the part number, N-Frame configuration, dimensions, pole count, voltage, A.I.C. rating, trip functions, mounting arrangement, rating plug, and terminal requirements. When those specifications match the existing equipment, the NDC3800T36W provides the form, fit, and functionality needed to keep the system operating as intended.
