FGA34040 - 40Amp Circuit Breaker

FGA34040 - 40Amp Circuit Breaker

The FGA34040 circuit breaker is a 40-amp, 3-pole molded case circuit breaker for your compatible electrical distribution equipment that requires an FGA I-Line frame, plug-in configuration, and thermal-magnetic circuit protection. For legacy equipment, careful matching matters: the catalog number, amperage, number of poles, voltage, AIC rating, frame type, mounting method, and dimensions must match the existing system's requirements. The FGA34040 is built to last and is a practical choice when the job calls for maintaining the specified form, fit, and function of a compatible FGA breaker installation.

Key Features and Benefits

• 40-amp rating: Intended for compatible circuits requiring a 40A molded case circuit breaker.
• 3-pole configuration: Provides three-pole circuit protection in electrical distribution applications designed for this configuration.
• FGA I-Line frame: A key identification point when matching the breaker to compatible existing equipment.
• Plug-in construction: Designed for equipment that accepts the corresponding I-Line plug-in breaker arrangement.
• Thermal-magnetic operation: Uses thermal and magnetic trip characteristics for circuit protection.

Material Compliance and Certifications

The supplied FGA34040 specifications did not include any specific UL, CSA, RoHS, REACH, or other certification or material-compliance status. These designations should not be inferred from the breaker family or part number. If a particular listing or material-compliance requirement is important to the application, confirm it in the breaker markings and applicable manufacturer documentation.

Where It Works Best

The FGA34040 40A 3-pole circuit breaker is best suited for compatible electrical distribution equipment that specifically requires an FGA I-Line frame, plug-in mounting arrangement, 40A rating, and thermal-magnetic molded case breaker design. It can be especially relevant when maintaining legacy equipment where preserving the correct form, fit, and electrical function is the priority.
