NDC3800T32W - 800 Amp Circuit Breaker

NDC3800T32W - 800 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the details matter. The NDC3800T32W is an 800-amp, 3-pole, Type NDC N-Frame molded-case circuit breaker for compatible electrical systems that require this configuration. It is HACR-rated and uses a thermal-magnetic electronic design with a non-interchangeable trip unit. You can adjust short-time pickup and short-time delay independently, providing the specified protection functions of this NDC configuration.

The NDC3800T32W is rated 65kA at 600VAC, 100kA at 480VAC, and 200kA at 240VAC. It measures 16 inches high, 8.25 inches wide, and 5.5 inches deep. Those dimensions, along with the frame, amperage, pole count, and interrupting rating, are worth checking carefully when matching a breaker to existing equipment. This unit is built to last and is especially useful when the job calls for maintaining the original form, fit, and function of a compatible legacy electrical system. One thing to keep in mind: the catalog number does not include the rating plug or lug terminals.

Material Compliance and Certifications

• The available specifications identify the NDC3800T32W as HACR rated. The supplied product data did not include additional material-compliance information or certifications, so do not assume UL, CSA, RoHS, REACH, or other compliance claims without supporting documentation.
• For an existing installation, verify the required ratings, certifications, and equipment requirements before putting the breaker into service.
  

Where It Works Best

• The NDC3800T32W 800A circuit breaker is a natural fit for maintenance and replacement work involving compatible legacy NDC N-Frame electrical equipment. It's especially useful when you need to keep the original equipment configuration instead of switching to a different breaker.
• Matching by part number is a useful starting point, but don't stop there. Check the 800A rating, three-pole configuration, N-Frame size, voltage, A.I.C. rating, trip functions, and physical dimensions against the existing breaker and equipment. Also check the required plug and lug terminal ratings separately.
