PBF31200 1200 Amp Circuit Breaker

PBF31200 1200 Amp Circuit Breaker

Finding the right breaker for older electrical equipment often comes down to one thing: matching the original specifications. The PBF31200 is a 1200A, 3-pole Type PBF AB DE-ION® circuit breaker made for 60-cycle AC 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 2000A to 6000A. The breaker measures approximately 22 inches high, 12 inches wide, and 9 inches deep. Those details are especially important when you're working with existing equipment, where the breaker must match the required footprint and electrical characteristics. For maintenance teams, electricians, and facilities keeping legacy electrical systems in service, the PBF31200 is a practical option when this specific Type PBF configuration is required. It was built to last and, in the right application, provides the form, fit, and function needed to maintain the original system setup.

Key Features and Benefits

• 1200A rating for compatible electrical distribution applications.
• 3-pole configuration for systems requiring this specific pole arrangement.
• Type PBF AB DE-ION® design for compatible legacy equipment.
• Rated 100k AIC at 600VAC and 480VAC and 125k AIC at 240VAC.

Material Compliance and Certifications

• Specific material-compliance information and certification details are not included in the available specifications for the PBF31200. Because markings and documentation may vary by individual unit and manufacturing period, they should be checked directly on the breaker or against the applicable product documentation.
• For installations subject to electrical codes, facility standards, or other regulatory requirements, have a qualified electrical professional verify that the breaker and its applicable certifications are appropriate for the equipment and application.

Where It Works Best

• The PBF31200 1200A circuit breaker is best suited to existing electrical equipment that calls for a 3-pole Type PBF breaker with matching ratings and dimensions. You'll typically encounter this type of breaker when maintaining older industrial or commercial electrical distribution equipment while keeping the original system configuration intact.
  
• Compatibility is the important part. Don't rely on the 1200A rating alone when determining fit. Check the PBF31200 against the breaker being replaced and the equipment documentation, paying attention to the part number, Type PBF design, three-pole configuration, voltage and AIC ratings, physical dimensions, 60 Hz frequency, and magnetic trip settings.
  
• When those requirements match, the PBF31200 can provide the form, fit, and function needed for a straightforward replacement in compatible legacy equipment.
