PBF31400 1400 Amp Circuit Breaker

PBF31400 1400 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, the details matter. The PBF31400 is a 1400A, 3-pole Type PBF AB DE-ION® circuit breaker designed for 60-cycle applications. Its interrupting ratings are 100k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC, with magnetic low/high trip settings of 2500A to 7000A. Physically, the breaker measures 22 inches high, 12 inches wide, and 9 inches deep. Those dimensions, along with the amperage, pole count, voltage, AIC ratings, and trip range, are important when checking it against an existing installation. For facilities maintaining compatible legacy electrical equipment, the PBF31400 can provide the form, fit, and function needed without changing the basic breaker specification the system was designed around. It's a straightforward piece of electrical equipment, built to last and made for applications that specifically call for this PBF configuration.

Material Compliance and Certifications

• Specific material compliance information, certifications, and agency listings were not provided in the available specifications for the PBF31400. We don't want to make assumptions about certifications that haven't been documented.
• If your facility or application requires a particular certification or material compliance standard, confirm those requirements before installation. The breaker should also be checked against the existing equipment specifications and applicable electrical requirements by a qualified electrical professional.

Where It Works Best

• The PBF31400 circuit breaker is a good fit for compatible legacy electrical systems that were designed around this particular Type PBF, 1400A, 3-pole configuration. This can include commercial and industrial electrical distribution equipment where maintaining the original breaker specifications is important.
  
• And with replacement breakers, amperage is only part of the story. A breaker marked 1400A isn't automatically the right match. Check the PBF type, three-pole configuration, voltage, AIC rating, magnetic trip range, frequency, physical dimensions, and equipment requirements against the breaker being replaced.
  
• When those specifications align, the PBF31400 can serve as a practical form, fit, and function replacement for the intended equipment.
