NB3800PR - 800 Amp Tri-Pac Circuit Breaker

NB3800PR - 800 Amp Tri-Pac Circuit Breaker

Need an NB3800PR circuit breaker for an existing electrical system? This NB breaker is rated at 800 amps and has a 3-pole configuration. Its interrupting rating is 200k A.I.C. at 240VAC, 480VAC, and 600VAC. When replacing a breaker in legacy equipment, the details matter. It isn’t enough to find the same amperage. The breaker must also match the application’s electrical requirements and physical configuration. The NB3800PR measures 22.25 inches high, 8.38 inches wide, and 7.25 inches deep, so check those dimensions against the existing equipment before installation. For systems that specifically call for the NB3800PR, this is a straightforward, built-to-last replacement option with the ratings and configuration needed to keep compatible equipment in service.

Material Compliance and Certifications

• The available product specifications did not include specific material compliance information, certifications, or agency listings. If your facility or application requires a particular certification or compliance standard, confirm the documentation for the exact NB3800PR before installation.

Where It Works Best

• The NB3800PR is best suited to existing electrical equipment designed for this Type NB breaker configuration. It can be a useful replacement for older distribution equipment when matching the original breaker’s 800A rating, 3-pole configuration, interrupting rating, and physical size is important.
• Before installation, confirm the part number and all electrical and dimensional requirements against the equipment being serviced. This helps avoid one of the most common problems with replacement circuit breakers: finding a breaker with similar ratings that isn’t actually the correct fit for the application.
