FJA34080 - 80Amp Circuit Breaker

FJA34080 - 80Amp Circuit Breaker

Finding the right replacement for your breaker is about more than matching the same general shape. FJA34080 is an 80-amp, 3-pole molded case circuit breaker built around the FJA I-Line frame with a plug-in configuration and PowerPact thermal-magnetic protection. For electricians, maintenance teams, and facility personnel, the important question is simple: do the amperage, poles, frame, connection, dimensions, and voltage-specific A.I.C. ratings match the equipment requirements? When they do, the FJA34080 delivers the specified form, fit, and function in a molded-case breaker built to last.

Key Features and Benefits

• 80-Amp Rating: Provides the specified 80A current rating for compatible electrical applications.
• 3-Pole Configuration: Designed with three poles for equipment requiring this particular breaker arrangement.
• FJA I-Line Frame: The FJA frame designation helps identify the correct physical and functional configuration when matching an existing breaker.
• Plug-In Configuration: Uses the specified plug-in connection for compatible I-Line equipment.
• PowerPact Thermal-Magnetic Protection: Incorporates the stated thermal-magnetic protection design in a molded case circuit breaker.

Where It Works Best

The FJA34080 80A circuit breaker is best suited to compatible legacy electrical distribution equipment that requires an 80-amp, 3-pole FJA I-Line plug-in molded case circuit breaker with the specified physical dimensions and interrupting ratings. This is especially relevant for maintenance and functional replacement work where retaining the required breaker frame, amperage, pole count, connection method, and footprint is essential.
