Eaton QBHW3100H - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton QBHW3100H, a 100 A, 240 V, 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 real-world reliability, it thrives in residential, commercial, and light industrial applications where steady protection and solid connections matter.

• Secure bolt-on mounting: engages the bus connection with a rugged, vibration-resistant fit that stays tight even in high-traffic or industrial environments. This eliminates the common issues caused by loose connections and reduces nuisance trips caused by movement.
• Thermal-magnetic trip unit: combines precise thermal protection with instantaneous magnetic trip action for severe faults, delivering stable, repeatable protection performance over time.
• Three-pole design for 3-phase circuits: ideal for commercial loads and any system requiring balanced protection across three phases, while still suitable for complex residential setups with multi-wire configurations.
• OEM-loadcenter compatibility: engineered to pair with matching Eaton loadcenters and panelboards, ensuring coordinated protection and a seamless retrofit or upgrade path.
• Clear specifications for planning: 100 A rating, 240 V, bolt-on mounting, molded case construction—all in a compact, dependable package designed for long service life.

Use cases and scenarios why this matters:

• Upgrading or expanding a panel in a commercial space where 3-phase circuits require robust, reliable protection and a secure mounting method.
• Retrofits or new installations in residential settings that demand a sturdy bolt-on solution for panels and loadcenters prone to vibration or movement.
• Applications in light industrial environments where minimizing downtime and ensuring rapid fault clearance are priorities.
