Eaton HBAX3100H - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton HBAX3100H is a 100A, 240V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for reliability in residential, commercial, and light industrial environments, this breaker pairs rugged construction with precise protection, making it a trusted choice for demanding electrical installations.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection ensures stable performance in busy equipment rooms and areas with equipment vibration, reducing movement that can affect long-term reliability.
• Thermal-magnetic trip unit provides stable, repeatable protection—the thermal element guards against nuisance trips from normal heat variation, while the magnetic element delivers instantaneous disconnection during short-circuit events.
• Three-pole design at 100 A, 240 V protects all hot legs in 240V systems and supports three‑phase applications or multi‑wire circuits that require simultaneous disconnection for safety and code compliance.
• OEM-loadcenter compatibility is engineered to fit with matching Eaton OEM loadcenters and panelboards, ensuring proper fit, electrical performance, and coordinated protection across the panel layout.
• Versatile applications—well-suited for residential panels, commercial electrical rooms, and light industrial feeds where reliable, predictable protection is essential.

Use cases you’ll appreciate include feeding subpanels, protecting branch circuits in utility rooms, or serving critical equipment in small commercial spaces. The HBAX3100H helps meet protection and disconnection requirements with consistent trip characteristics across a range of loads and temperatures, giving technicians confidence during installation and during fault events.

Why this matters — The bolt-on mounting delivers a durable, vibration-resistant connection that remains secure over time, while the molded-case design promotes predictable thermal performance. This combination supports reliable operation in panelboards and loadcenters, reducing maintenance needs and helping you maintain electrical system integrity.
