Eaton QBHW3030HS - 30 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton QBHW3030HS — a 30A, 240V, 3-pole bolt-on molded case circuit breaker engineered to anchor your electrical system with dependable, precise protection. Built for panelboards and loadcenters, this unit is ready to handle the demands of modern electrical installations with confidence.

Key to its reliability is a secure bolt-on mounting that delivers a rigid, vibration-resistant bus connection. In demanding environments—where panels experience vibration or movement—the QBHW3030HS maintains a solid connection, reducing the risk of loose terminals and intermittent trips.

The thermal-magnetic trip unit delivers stable, repeatable protection performance. By combining thermal sensing with magnetic trip action, it quickly responds to short-circuit events while avoiding nuisance trips due to normal temperature fluctuations. This means fewer unexpected outages and more consistent protection for downstream equipment.

Compatibility matters. The QBHW3030HS is designed to work with matching OEM load centers and panelboards, ensuring a seamless fit and reliable operation within your existing electrical architecture. This alignment helps simplify maintenance and upgrades, so you can expand or reconfigure without compatibility concerns.
