PBF31000 1000 Amp Circuit Breaker

PBF31000  1000 Amp Circuit Breaker

Need a PBF31000 circuit breaker for an existing electrical system? This 1000A, 3-pole Type PBF AB DE-ION® circuit breaker is designed for applications where matching the original breaker's size, ratings, and operating characteristics is important. The PBF31000 operates at 60 cycles and is rated 100k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC. Magnetic low/high trip settings range from 1500A to 5000A. At approximately 22 inches high, 12 inches wide, and 9 inches deep, it has the dimensions needed for compatible PBF equipment. This makes it a useful option for electricians, maintenance departments, and facility teams working with established electrical distribution systems. When the existing equipment calls for these specifications, the PBF31000 provides the form, fit, and function needed for the application. It's a straightforward, built-to-last breaker made to handle the job it was designed for.

Where It Works Best

• The PBF31000 makes the most sense for existing or legacy electrical distribution equipment designed for a compatible Type PBF 1000A, 3-pole circuit breaker. Typical applications may include industrial plants, manufacturing facilities, commercial buildings, and other locations where older electrical equipment remains in service.
  
• For replacement applications, matching the details is especially important. Check the part number, amperage, number of poles, AIC and voltage ratings, magnetic trip range, dimensions, and connection configuration against the breaker being replaced and the equipment requirements. If those specifications match, the PBF31000 can provide the required form, fit, and function without changing the intended system configuration.
