QBHW2020C - 20 Amp Circuit Breaker

QBHW2020C - 20 Amp Circuit Breaker

Take control of your electrical protection with the QBHW2020C 20‑Amp Bolt‑On Thermal Magnetic Circuit Breaker — the dependable choice for homeowners, contractors, and facility managers who demand safety, performance, and peace of mind. This breaker combines thermal overload and magnetic short‑circuit protection so your system is defended under stress. Engineered with HACR‑rating and advanced Quicklag response features, it steps in fast when faults occur — whether it’s in residential panels, light industrial settings, or demanding HVAC systems.

Key Features and Benefits

• Thermal & Magnetic Dual Protection – The built‑in thermal element guards against prolonged overloads, while the magnetic component reacts instantly to sudden short circuits.
• HACR Rated – Certified to handle heating, air conditioning, and refrigeration (HACR) loads, ensuring reliable performance in appliances and systems where those loads are heavy.
• Quicklag Technology – Reacts faster than standard breakers, which helps minimize damage during electrical faults and keeps connected equipment safer.
• Switching Neutral Leg – Adds flexibility in wiring and improves safety since the neutral path will open reliably under fault conditions.
• Bolt‑On Design – Secure installation into panels with a compact form factor; great for retrofits or when upgrading older circuit panels without changing the panel enclosure.

Where It Works Best

• Residential service panels and subpanels
• Commercial environments with mixed loads (lighting, HVAC, refrigeration)
• Light industrial facilities needing dependable overload & short‑circuit defense
• HVAC, refrigeration systems, or other high inrush‑current loads
• Retrofits or upgrades to existing electrical panels where space is limited but performance requirements are not negotiable
