Square D 30072-452-02-A Through Door Disconnect

Square D 30072-452-02-A Through Door Disconnect is a door-mounted disconnect switch from Square D (Schneider Electric) designed to be installed through an enclosure door to provide a mechanical isolation point for a circuit within Square D panel systems. It is intended for through-door installation, allowing maintenance personnel to disconnect power without opening the main enclosure, supporting safer servicing of equipment inside industrial and commercial control panels. The device sits within Square D’s family of through-door disconnect components and aligns with the brand’s broader line of operating mechanisms and disconnect switches, which are widely used in enclosure-based power distribution and control applications. Typical use cases include control panels and switchgear where a dedicated, door-accessible disconnect is required for safe maintenance, testing, or emergency shutdowns; always verify exact compatibility, ratings, and mounting requirements with the official Square D literature for your enclosure and the 30072-452-02-A part is.
