Eaton HFD1025 - 25 A, 277 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Eaton HFD1025 is a 25A, 277V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built to endure the realities of commercial and light industrial environments, this breaker provides reliable protection against overcurrents and short circuits while staying securely connected to the bus through a rigid bolt-on mounting.

What makes this breaker stand out is its combination of a bolt-on mounting system and a thermal-magnetic trip unit. The bolt-on design minimizes bus connection impedance and resists loosening in vibration-prone installations, while the thermal-magnetic trip delivers stable, repeatable protection across changing loads. This means fewer nuisance trips and consistent performance for critical circuits like lighting, HVAC controls, and small machinery in commercial spaces.

Compatibility matters. The HFD1025 is engineered to work seamlessly with matching OEM load centers and panelboards, ensuring a streamlined upgrade or replacement path without sacrificing reliability or electrical clearance. It’s the practical choice for upgrades, retrofits, or new installations where 277V single-pole protection is required.

Intended uses and ideal recipients

• Residential-equivalent, commercial, and light industrial electrical panels requiring single-pole 25A protection
• Panels and load centers that use bolt-on molded case breakers for secure, vibration-resistant operation
• Applications where 277V circuits are common, such as lighting feeders, fans, motors, and control circuits
