Square D H361N Safety Disconnect Switch Type 1

Square D H361N is a heavy-duty fusible safety disconnect switch rated for 30 A at up to 600 V AC, designed for indoor use in a NEMA 1 enclosure with three poles and four conductors for three-phase systems. As a Type 1 (NEMA 1) disconnect, it provides a single-throw mechanism to isolate power to the load and is configured as a 3-pole, 4-wire device for 3-phase circuits. This fusible switch accepts compatible Square D fuse provisions (Class H or K fuses per Schneider Electric data sheets), enabling field protection coordination with auxiliary fusing options; confirm the exact fuse family to match your protection requirements. Typical applications include motor control, feeders, and power isolation in industrial or commercial panels where a compact, indoor, fusible disconnect is required.
