Eaton HBAX3090H - 90 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable protection in panelboards and loadcenters, the Eaton HBAX3090H delivers 90A, 3-pole coverage with a bolt-on design that ensures a secure, vibration-resistant bus connection. This switchgear component is built to handle demanding branch circuit overcurrent and short-circuit scenarios with precision and consistency.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays locked in even in environments with equipment movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance, combining fast short-circuit response with reliable overload coordination.
• OEM-ready compatibility designed to work seamlessly with matching OEM loadcenters and panelboards for straightforward installation and reliable operation.
• Diverse application scope suitable for residential, commercial, and light industrial distribution where robust branch circuit protection is required.

The HBAX3090H family by Eaton is purpose-built for installers seeking a hardened, drop-in solution for panelboard and loadcenter protection. With its 3-pole configuration, this unit protects multi-wire circuits and provides coordinated protection across three phase paths, helping to prevent damage from overcurrent and short circuits in critical electrical systems.

Why this matters in real-world setups

In a home subpanel, the HBAX3090H can guard three-phase branch circuits or evenly protect three hot legs in a shared distribution layout, reducing nuisance trips and ensuring quick, reliable shutdown during faults. In small commercial or light industrial panels, its bolt-on design simplifies installation in crowded enclosures where space and wiring management are at a premium. The combination of secure mounting and a trip unit tuned for stability translates to fewer re-trips, improved system uptime, and predictable protection performance over the life of the installation.
