Information About QOB320GFI
The QOB320GFI is a ground-fault protecting circuit breaker from the Schneider Electric Square D QO series designed for enhanced personnel protection and reliable circuit interruption. It combines thermal-magnetic overcurrent protection with Class A ground-fault sensing to trip at 6 mA, reducing the risk of electrical shock. The breaker uses a bolt-on construction with box lug terminations to ensure stable electrical connections in compatible QO load centers. It is commonly applied in commercial and light industrial systems where multi-pole ground-fault protection and compact panelboard integration are required.
Key Features
- Three-pole configuration: Supports protection of multi-phase branch circuits in 208Y/120 VAC systems.
- 20 amp current rating: Suitable for control, lighting, and specialty circuit applications.
- Class A ground-fault protection: Trips at 6 mA to enhance personnel safety.
- Thermal-magnetic trip mechanism: Provides coordinated response to overloads and short-circuit conditions.
- 10 kA interrupting capacity: Ensures dependable fault interruption at rated system voltage.
- Bolt-on mounting design: Delivers secure mechanical and electrical attachment within QO panelboards.
- VisiTrip™ indication: Provides clear visual identification of a tripped breaker.
The QOB320GFI delivers the reliability and precision required for combined overcurrent and ground-fault protection in Schneider Electric Square D QO electrical distribution systems.
