    Description

    Mini Circuit Breaker 20A 3-Pole 120/240VAC 10kA Plug-in Mount

    Features

    • The QO320 features Schneider Electric s exclusive red Visi-TripTM indicator, which instantly flags a tripped breaker among a row of many. This visual shortcut saves industrial technicians and homeowners significant troubleshooting time, allowing for faster power restoration and less downtime during electrical faults.
    • Designed as a dedicated 3-pole breaker, this unit ensures that if any single phase experiences an overcurrent event, all three poles trip simultaneously. This "common trip" functionality is critical for protecting expensive 240V or 208V three-phase motors and machinery from "single-phasing" damage, which can lead to motor burnout and costly repairs.
    • This breaker utilizes the industry-standard QO "Plug-On" mounting system, engineered for a secure, bolt-free connection to the bus bar. It is specifically compatible with QO, QOT, and QO3 load centers and NQ-type panelboards, ensuring a fast, reliable installation that maintains the integrity of your Square D distribution system.
    • The QO320 utilizes a sophisticated thermal-magnetic trip mechanism that provides a calibrated delay for high-inrush currents typical of small motors or HVAC compressors while offering nearly instantaneous protection against short circuits. This dual-action response ensures your equipment starts reliably while maintaining a rigorous safety envelope for your wiring.
