Schneider Electric FA36030 Shunt Trip Circuit Breaker

Schneider Electric FA36030 is a three-pole, 30-amp molded-case circuit breaker in the Square D I-Line FA family, designed for 600 VAC (250 VDC) service with plug-on mounting in FA/I-Line panelboards to protect three-phase feeders and motor circuits in commercial and light industrial installations. It uses a thermal-magnetic trip mechanism and offers an interrupt rating up to 14 kA at 600 VAC, aligning with common distribution-level protection requirements. The shunt-trip variant, marketed as FAL36030 (and variants such as FAL360301021), includes a dedicated shunt-release coil for remote disconnection, typically rated around 24 VDC, enabling fast isolation from a control room or safety interlock. Typical applications include feeders for motors, compressors, and other three-phase equipment in industrial or large commercial panels, where remote trip capability and straightforward replacement in I-Line enclosures are valued. Field installation is straightforward in FA/I-Line panels, supporting coordinated protection with other Square D protection devices.
