FJA34100 - 100Amp Circuit Breaker

FJA34100 - 100Amp Circuit Breaker

Finding the right breaker for your existing electrical equipment means matching the details that matter. The FJA34100 circuit breaker is a 100-amp, 3-pole molded case circuit breaker with an FJA I-Line frame, plug-in configuration, and PowerPact thermal-magnetic protection. For systems specifically designed around these characteristics, the FJA34100 provides the form, fit, and function needed for a properly matched replacement.

Key Features and Benefits

• 100-Amp Rating: Rated at 100A for compatible electrical equipment requiring this specific current rating.
• 3-Pole Configuration: Three-pole construction provides a clear matching point when identifying the correct breaker for existing equipment.
• FJA I-Line Frame: Designed around the specified FJA I-Line frame configuration for compatible applications.
• Plug-In Design: Uses a plug-in configuration, making connection type an important part of the compatibility check.
• PowerPact Thermal-Magnetic Protection: Includes the specified thermal-magnetic protection in a molded-case circuit breaker design.

Material Compliance and Certifications

The supplied specifications for the FJA34100 did not include any specific UL, CSA, RoHS, REACH, or other certification or material-compliance information. Do not assume those certifications from the model number or product type alone. Where a particular listing or compliance standard is required, verify the markings on the breaker and consult the appropriate authoritative product documentation before use.

Where It Works Best

The FJA34100 100A circuit breaker is best suited for compatible legacy electrical distribution equipment that requires a 3-pole, 100-amp FJA I-Line plug-in molded case circuit breaker with the same physical footprint and interrupting ratings. This matters most in maintenance and functional replacement situations where preserving the original breaker's form, fit, electrical ratings, and connection style is critical.
