Eaton FD1025L (347 V) - 25 A, 347 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton FD1025L (347 V) 1-pole bolt-on molded case circuit breaker—a purpose-built solution for dependable branch circuit protection in panelboards and loadcenters. With a 25 A rating at 347 V, this device is engineered to safeguard single-phase circuits in commercial and residential environments while standing up to the demands of everyday electrical load.

• Bolt-on mounting: provides a rigid, vibration-resistant bus connection that stays secure even in busy electrical panels.
• Thermal-magnetic trip: combines time-delayed thermal protection with instantaneous magnetic tripping for stable, repeatable protection against both overloads and short circuits.
• 1-pole design: targeted protection for a single live conductor, simplifying replacement in compatible Eaton panel ecosystems.
• Molded case construction: durable enclosure designed to endure common panelhouse environments and resist wear over time.
• OEM compatibility: specifically designed to integrate with matching Eaton loadcenters and panelboards for a seamless, worry-free installation.
• 347 V rating: ideal for commercial distribution networks and lighting circuits that operate at 347 V, a common configuration in non-residential settings.
• Versatile application: suitable for residential, commercial, and light industrial electrical protection needs.

Why this matters in real-world use: when circuits face overloads or sudden surges, the FD1025L trips to prevent insulation damage, nuisance outages, and fire risks. The thermal portion accounts for normal, steady loading, while the magnetic portion delivers an instantaneous response to short circuits. The result is safer equipment operation, reduced downtime, and greater peace of mind in everyday panel operation.

Use cases and ideal scenarios

• Upgrading existing panelboards in offices or retail spaces to improve protection on critical lighting and receptacle circuits.
• Installing in new commercial projects that employ 347 V distribution networks, where reliable single-pole protection is needed.
• Field service and maintenance work requiring replacement or retrofitting within Eaton panel ecosystems.

Compatibility and installation notes

The FD1025L is a bolt-on breaker designed to work with Eaton’s family of panelboards and loadcenters. Confirm that your panel supports bolt-on devices and that the 25 A, 347 V rating matches your circuit design. For best results, follow Eaton’s installation instructions to ensure proper alignment with the bus bars and secure mounting within the panel enclosure.
