Commander QBH2100 - 100 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Commander QBH2100 — a precise, reliable 2-pole, 100A, 240V bolt-on molded case circuit breaker designed to protect your electrical distribution with confidence. Engineered for panelboards and loadcenters, this breaker delivers dependable branch-circuit overcurrent and short-circuit protection where it matters most.

Why the QBH2100 stands out

• Secure bolt-on mounting creates a rigid, vibration‑resistant bus connection, reducing the risk of loose contacts and unpredictable trips in environments with equipment vibration or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying temperatures and loads. The thermal element handles sustained overloads, while the magnetic element responds quickly to short circuits, helping prevent damage to wiring and devices.
• OEM-ready compatibility is built for seamless integration with matching Commander OEM loadcenters and panelboards, simplifying upgrades, retrofits, and service replacements.
• Versatile for multiple sectors suited for residential, commercial, and light industrial applications, delivering consistent performance in a wide range of electrical distribution systems.
• Structured protection for branch circuits targets overcurrent and short-circuit events, helping protect downstream devices, wiring insulation, and overall system reliability.
