Why this bolt-on 2-pole breaker stands out

For panels designed to accept bolt-on protection devices, the FDA24045 offers a secure, robust mounting that stays aligned under vibration and load fluctuations. The 277V rating makes it particularly well-suited for commercial lighting circuits and distribution paths in office complexes, shopping centers, and other non-residential settings. The 45A capacity strikes a careful balance between protecting circuits from faults and supporting reliable operation for standard motor and lighting loads.

Ideal use cases

• Maintenance, retrofit, or replacement in existing panels that require a 2-pole, 277V, 45A bolt-on breaker with matching specs.
• Protection for two hot legs on 277V commercial lighting and related distribution circuits.
• Upgrading panel protection where field-fitted, bolt-on devices are specified by the enclosure manufacturer.

How to ensure a perfect fit

Always verify compatibility by cross-referencing the part number. Confirm that your enclosure supports bolt-on breakers and that the panel’s rated voltage and required amperage align with the FDA24045’s specifications. The part number is the most reliable reference for compatibility.

Practical installation and maintenance tips

• Power down and lock out the circuit before removing or installing the breaker to ensure safe handling.
• Consult your panel’s documentation to confirm mounting footprint and any torque recommendations for bolt-on connections.
• Keep spares of FDA24045 on hand for scheduled maintenance and rapid replacements to minimize downtime.
