Commander BQGF20 20 Amp GFCI Circuit Breaker

The Commander BQGF20 20 Amp GFCI Circuit Breaker is engineered to deliver dependable ground-fault and overcurrent protection for single-pole circuits at 120V. Designed for panelboards and loadcenters, this bolt-on molded case breaker provides a sturdy, vibration-resistant connection and reliable protection where it matters most—near water-prone or moisture-sensitive spaces and in everyday electrical installations.

Why this breaker stands out

• GFCI protection in a compact, 1-pole design: Specifically built to guard against ground faults on 120V circuits, helping prevent shock hazards in kitchens, bathrooms, laundry areas, outdoors, and other moisture-adjacent locations.
• Bolt-on mounting for a rock-solid connection: Secure attachment to the bus bar reduces vibration and arcing risk, contributing to long‑term circuit reliability in residential panels, commercial boxes, and light industrial setups.
• Thermal-magnetic trip unit for stable performance: Consistent trip thresholds ensure predictable response to overcurrent and short-circuit conditions, safeguarding connected equipment and improving panel longevity.
• OEM panel compatibility: Designed to integrate with matching Commander/OEM loadcenters and panelboards, simplifying selection and installation in existing systems.
• Versatile across settings: Ideal for residential, commercial, and light industrial applications where dedicated ground-fault protection is required on a dedicated 20A branch circuit.

Perfect use cases

• Protect a dedicated kitchen countertop or breakfast nook circuit that requires both overcurrent and ground-fault protection.
• Guard bathroom and laundry room outlets where moisture exposure elevates shock risk.
• Provide outdoor or garage circuit protection for tools and lighting in spaces with higher humidity levels.
• Upgrade existing panelboards to include GFCI protection without replacing entire panels, thanks to compatible bolt-on design.
