FJA34050 - 50Amp Circuit Breaker

FJA34050 - 50Amp Circuit Breaker

When you're replacing a breaker in legacy electrical equipment, small details often determine whether the part is right for the job. The FJA34050 circuit breaker is a 50-amp, 3-pole molded case circuit breaker with an FJA I-Line frame, plug-in configuration, and PowerPact thermal-magnetic protection. The FJA34050 is built to last and is well suited to replacement situations where the existing system calls for this particular combination of amperage, pole count, frame style, connection method, dimensions, and interrupting capacity.

Key Features and Benefits

• 50-Amp Rating: Provides the specified 50A current rating for compatible electrical distribution applications.
• Three-Pole Configuration: Designed with three poles to match equipment requiring this breaker arrangement.
• FJA I-Line Frame: The FJA I-Line configuration provides an important identification point when matching an existing breaker.
• Plug-In Connection: Uses the specified plug-in design for equipment intended to accept this connection style.
• Thermal-Magnetic Protection: Features the supplied PowerPact thermal-magnetic protection configuration.
