FGA34045 - 45Amp Circuit Breaker

FGA34045 - 45Amp Circuit Breaker

When you're replacing a breaker in existing electrical equipment, the details have to line up. The FGA34045 circuit breaker is a 45-amp, 3-pole molded case circuit breaker with an FGA I-Line frame, plug-in configuration, and PowerPact thermal-magnetic design. Rather than relying on appearance alone, technicians can compare the catalog number and key electrical characteristics with the breaker being replaced and the equipment's requirements. For installations designed around the FGA configuration, this breaker is built to last while providing the specified form, fit, and circuit-protection function.

Key Features and Benefits

• 45A current rating: Designed for compatible electrical applications requiring a 45-amp breaker.
• 3-pole configuration: Provides three-pole circuit protection where the equipment specifies this arrangement.
• FGA I-Line frame: Helps identify the correct frame configuration when matching an existing installation.
• Plug-in design: Intended for compatible equipment designed to accept the corresponding I-Line plug-in breaker.
• Thermal-magnetic protection: Uses thermal and magnetic trip characteristics for circuit protection.
• Replacement-focused design: Well suited to situations where matching the original breaker's form, fit, electrical ratings, and function is the priority.

Material Compliance and Certifications

The supplied specifications for the FGA34045 did not include specific UL, CSA, RoHS, REACH, or other certification or material-compliance information. Do not assume those designations based on the breaker family, type, or appearance.

Where It Works Best

The FGA34045 45A 3-pole circuit breaker is best suited to compatible electrical distribution equipment specifically designed around an FGA I-Line frame and plug-in breaker configuration. It is particularly relevant for maintaining legacy installations where preserving the correct breaker dimensions, amperage, pole configuration, connection method, and interrupting capacity is essential.
