QBHW2020S - 20 Amp Circuit Breaker

QBHW2020S - 20 Amp Circuit Breaker

Keep your industrial electrical system safe and running smoothly with the Eaton QBHW2020S 20‑amp thermal‑magnetic circuit breaker. Designed to protect against both overloads and short circuits, this two‑pole breaker works across 120V, 208V, and 240V systems, making it a versatile choice for many demanding applications. With a high interrupt rating of 22 kAIC, it can stop high fault currents fast, helping prevent equipment damage and minimizing downtime. Its compact size means installation is easier even where space is limited, yet it delivers serious protection and meets top industry standards.

Key Features and Benefits

• High Fault‑Current Protection: 22 kAIC interrupt rating ensures that the breaker can interrupt dangerous surges safely.
• Dual Protection Modes: Combines thermal overload detection with magnetic short‑circuit response so both slow build‑ups and sudden spikes are handled.
• Compatible with Multiple Voltages: Rated for 120V, 208V, 240V systems, making it useful in a wide range of industrial or commercial electrical panels.
• Space‑Saving Construction: Measures only 3.6″ × 4.8″ × 2.2″ and weighs approximately 0.8 lb, so fitting into tight panels is simpler.
