FJA34030 - 30Amp Circuit Breaker

FJA34030 - 30Amp Circuit Breaker

Replacing a breaker in your existing electrical equipment comes down to getting the details right—not simply finding a part that looks similar. The FJA34030 circuit breaker combines a 30-amp rating, three-pole configuration, FJA I-Line frame, plug-in connection, and PowerPact thermal-magnetic protection in a molded case design. For maintenance teams, electricians, and facility personnel matching an existing FJA breaker, checking the catalog number alongside amperage, pole count, frame style, connection method, dimensions, system voltage, and required A.I.C. rating helps avoid guesswork.

Key Features and Benefits

• 30-Amp Rating: Provides the specified 30A current rating for compatible applications requiring this exact capacity.
• Three-Pole Design: Configured with three poles for electrical distribution equipment designed around this breaker arrangement.
• FJA I-Line Frame: The FJA frame designation and I-Line configuration are key details when matching an existing breaker.
• Plug-In Connection: Uses the specified plug-in design, making connection style an easy specification to confirm during compatibility checks.
• Thermal-Magnetic Protection: PowerPact thermal-magnetic operation provides the stated protection method within the molded case breaker.

Material Compliance and Certifications

The supplied specifications for the FJA34030 did not include specific UL, CSA, RoHS, REACH, or other certification or material-compliance information. Do not infer those certifications from the FJA designation, product family, or specifications of similar breakers. Where a particular listing, certification, or compliance requirement applies, confirm the markings on the individual breaker and consult the appropriate authoritative product documentation.

Where It Works Best

The FJA34030 30A 3-pole molded case circuit breaker is best suited to compatible legacy electrical distribution equipment requiring an FJA I-Line frame, plug-in configuration, 30-amp rating, and matching physical dimensions. It makes sense for maintenance and replacement situations where the objective is to preserve the existing equipment's required form, fit, and circuit-protection function.
