Schneider Electric D326N Fusible Safety Disconnect Switch

Schneider Electric's Square D D326N is a general-duty fusible safety disconnect switch rated for 600 A at 240 V AC. The device is a 3-pole, 4-wire (with neutral) configuration housed in a Type 1 enclosure, designed for indoor installation in commercial and industrial environments. As a fusible disconnect, it provides an isolated power-off point with fuse protection for equipment such as motors and power-distribution circuits, enabling safe maintenance and servicing. The D326N is part of Square D's family of safety switches, offering a simple, clearly identifiable means to shut off power to protected loads and to accommodate reliable fault protection. This unit supports applications requiring a robust, code-compliant disconnect in control panels, machine rooms, and service equipment installations where a dedicated, switch-based disconnection is needed at the line side of loads.
