QBHW2050S - 50 Amp Circuit Breaker

QBHW2050S - 50 Amp Circuit Breaker

The Eaton QBHW2050S is a heavy-duty two‑pole circuit breaker engineered to deliver reliable protection for both your home and business. Designed to work with 120V, 208V, and 240V electrical systems, it carries a 50‑amp capacity and features a 22 kA interrupting rating. Rather than waiting for damage to occur, it acts fast—guarding your wiring and equipment from overloads, short circuits, and electrical faults. Whether you’re upgrading existing panels or outfitting new installations, the QBHW2050S gives steady, trustworthy performance.

Key Features and Benefits

• High Fault Current Handling (22 kAIC): With its high interrupting capacity, this breaker is built to cut off power safely during extreme fault conditions—protecting both installer and property.
• Thermal‑Magnetic Trip Mechanism: Combines a heat‑sensitive element for long‑term overloads with a magnetic sensor that reacts to sudden surges—balancing protection and immediate response.
• Dual‑Voltage Compatibility: Works across 120V, 208V, and 240V systems, so it fits a wide range of electrical panels and setups without fuss.
• Space‑Saving Form Factor: Despite its capabilities, its compact size allows for easier installation into panelboards, helping maintain clean, efficient layouts.
  
• Enhanced Safety Control with Shunt Trip: Built‑in shunt trip feature offers advanced control—allowing remote disconnection or integration with safety systems for more demanding applications.
