FGA34090 - 90Amp Circuit Breaker

FGA34090 - 90Amp Circuit Breaker

For legacy electrical distribution equipment, a similar-looking breaker may not be the right match. The FGA34090 circuit breaker is defined by a specific combination of electrical and physical characteristics: a 90-amp rating, three-pole configuration, FGA I-Line frame, plug-in connection, and PowerPact thermal-magnetic protection. If you're replacing an FGA breaker, check more than the part number—current rating, pole count, frame, mounting style, dimensions, system voltage, and required interrupting capacity all matter.

Key Features and Benefits

• 90A Current Rating: Intended for equipment requiring a 90-amp circuit breaker.
• Three-Pole Configuration: Provides the specified 3-pole arrangement for compatible electrical distribution applications.
• FGA I-Line Frame: Gives maintenance personnel an important mechanical reference when matching an existing FGA breaker.
• Plug-In Connection: Designed around the specified plug-in configuration for equipment that accepts this breaker format.
• PowerPact Thermal-Magnetic Protection: Combines the specified thermal-magnetic protection characteristics in the FGA molded case design.

Material Compliance and Certifications

No specific UL, CSA, RoHS, REACH, or other certification or material-compliance information was provided for the FGA34090. Do not infer these credentials from the FGA product type or from similar-looking breakers. If a particular listing or material standard is required for the installation, confirm the breaker's markings and consult applicable authoritative product documentation.

Where It Works Best

The FGA34090 90A 3-pole molded case circuit breaker is best suited to compatible legacy electrical distribution equipment designed for the FGA I-Line frame and plug-in configuration. It's especially relevant when maintaining an existing installation where the goal is to preserve the required breaker format, physical footprint, electrical ratings, and protection characteristics.
