General Electric THFP321L Fusible Panelboard Switch

The GE THFP321L is a fusible panelboard switch from General Electric, designed for installation in electrical distribution panels where a reliable fuse-based disconnect is required to protect and control circuits in commercial and industrial environments. With a rating of 30 amperes at 240 volts and described as three-phase (3P), it supports standard GE panelboard configurations and provides a clearly defined point of isolation for maintenance, fault clearance, system testing, and safe power-down procedures. As a panelboard component, the THFP321L integrates into GE panelboard ecosystems, enabling coordinated protection alongside other GE components and simplifying wiring within the enclosure by aligning with common distribution practices for 3P, 240V circuits. This model is explicitly suited to installations requiring a dedicated, rated disconnect in a GE system, delivering a straightforward solution for protecting upstream equipment while allowing technicians to de-energize a circuit quickly and safely.
