ND3800T32W - 800 Amp Circuit Breaker

ND3800T32W - 800 Amp Circuit Breaker

The ND3800T32W is an 800-amp, 3-pole N-Frame molded-case circuit breaker for electrical equipment using the Type ND configuration. For replacement jobs, the key is matching the breaker to the existing equipment, and this model provides several specifications to check before installation.

It has an interrupting rating of 25 kA at 600 VAC, 50 kA at 480 VAC, and 65 kA at 240 VAC. The breaker is also HACR rated and has non-interchangeable trip units, along with independently adjustable short-time pickup and delay.

Physically, the ND3800T32W measures 16 inches high, 8.25 inches wide, and 5.5 inches deep. Those dimensions matter when you're working with existing switchgear or distribution equipment where there's little room for variation.

The catalog number does not include a rating plug or lug terminals, so keep that in mind when comparing this breaker with the unit already installed.

This breaker makes sense when you're maintaining older equipment and need the correct N-Frame configuration, rather than trying to substitute something not designed for the application. It's built to last and intended for electrical systems that match its ratings and configuration.

Material Compliance and Certifications

• The information provided for the ND3800T32W identifies it as HACR-rated. No other certifications or material-compliance declarations were provided, so don't assume any. If your job requires a particular approval or standard, check the breaker label and applicable documentation before installation.
  

Where It Works Best

• The ND3800T32W is primarily a replacement option for compatible legacy electrical equipment using the Type ND N-Frame configuration. You may find it in commercial, industrial, HVAC, and electrical distribution applications, provided the equipment calls for these exact electrical and physical specifications.
• Before replacing an existing breaker, compare the frame, amperage, number of poles, voltage, AIC rating, dimensions, trip configuration, rating plug, and terminal requirements. With older equipment especially, those details are more important than simply finding another 800-amp breaker.
