NB31000PR - 1000 Amp Circuit Breaker

NB31000PR - 1000 Amp Circuit Breaker

Finding the right breaker for existing equipment usually comes down to the details. The NB31000PR is a Type NB, 3-pole circuit breaker rated at 1000 amps. Its interrupting ratings are 22k AIC at 600VAC, 30k AIC at 480VAC, and 42k AIC at 240VAC. This breaker is intended for applications that require the NB31000PR to match the existing electrical system. That makes it useful for maintenance and replacement work on compatible legacy equipment. Rather than changing the original setup, you can match the part number, pole configuration, amperage, voltage, AIC rating, and physical fit to the breaker already specified for the equipment. Built to last and designed for its intended application, the NB31000PR provides a straightforward replacement option when the specifications line up.

Material Compliance and Certifications

• The available product specifications did not include material compliance and certification information. If your installation has specific certification, regulatory, or material requirements, confirm those requirements separately before selecting the breaker.

Where It Works Best

• The NB31000PR 1000A circuit breaker suits existing electrical distribution systems that call for this particular Type NB configuration. It makes the most sense for maintenance and replacement situations where the goal is to keep the equipment's established breaker setup intact.
• For replacement applications, check more than the amperage. Confirm the part number, 3-pole configuration, 1000A rating, operating voltage, AIC rating, and physical fit against the equipment requirements before installation.
