NDC3800T33W - 800 Amp Circuit Breaker

NDC3800T33W - 800 Amp Circuit Breaker

The NDC3800T33W is an 800-amp, 3-pole N-Frame molded case circuit breaker for use in compatible electrical equipment. If you’re replacing an existing Type NDC breaker, here are the key details: frame, amperage, pole count, interrupting ratings, dimensions, and trip functions. This breaker is HACR rated and uses thermal-magnetic protection with a non-interchangeable trip unit. It also includes adjustable short-time pickup with an I²t short-delay ramp.

Interrupting capacity depends on system voltage. The NDC3800T33W is rated 65 kA at 600 VAC, 100 kA at 480 VAC, and 200 kA at 240 VAC. Physically, it measures 16 inches high, 8.25 inches wide, and 5.5 inches deep. Check those dimensions carefully when using the breaker as a replacement in existing or legacy equipment. The catalog number does not include a rating plug or lug terminals. Built to last, the NDC3800T33W is a practical choice when your application specifically calls for its N-Frame configuration and electrical characteristics.

Material Compliance and Certifications

• The supplied specifications identify the NDC3800T33W as HACR rated. No other material-compliance information or certifications were provided, so do not assume additional certifications. Where a particular approval or compliance standard is required, confirm it against the breaker nameplate and applicable product documentation.

Where It Works Best

• The NDC3800T33W is best suited to existing and legacy electrical equipment that specifically requires a Type NDC, N-Frame, 800A, 3-pole circuit breaker with matching trip characteristics and interrupting ratings. It can be particularly useful when maintaining equipment where the goal is to preserve the original form, fit, and function.
• Before using it as a replacement, check more than the part number. Compare the frame, amperage, poles, system voltage, A.I.C. rating, physical dimensions, trip functions, rating plug requirements, and terminal requirements with the existing equipment. Always match electrical equipment to the requirements of the specific installation.
