ZINSCO QSF QSF6033 600 AMP 240V FUSIBLE F PANELBOARD SWITCH HARDWARE

Description:

The Zinsco QSF6033 is a 600 Amp, 3-pole fusible panelboard switch designed for use in Zinsco / GTE Sylvania distribution equipment. It operates on 240V systems and is part of the QSF series, engineered for panelboard mounting in high-capacity electrical systems. This switch utilizes a fusible design, allowing the use of Class RK1 or RK5 fuses for enhanced overcurrent protection and fault interruption. It provides reliable switching and protection for heavy-duty applications, with integrated bus connections and robust construction suited for industrial environments.

Applications:

The Zinsco QSF6033 panelboard switch is commonly used in commercial and industrial electrical distribution systems where high current capacity (600A) is required. Typical applications include main distribution panels, feeder circuits, switchboards, and large machinery power systems. Its fusible design makes it suitable for environments requiring both switching and fuse-based protection in a single unit.
