Technical Parameters Mechanical Shaft Compatibility: 6 mm square shaft. Handle Length: ~65 mm ergonomic grip. Mounting: Mounted on front of panel or enclosure; shaft ordered separately to match panel thickness and internal mechanism. Operation: Manual ON/OFF rotation controlling the connected disconnect switch. Environmental & Protection Protection Rating: High ingress protection suitable for panel front — withstands dust and water exposure. NEMA/IEC Ratings: Compatible with typical industrial enclosure standards (e.g., outdoor/indoor environments requiring NEMA 1, 3R, 12 levels of protection). Durability: Designed for industrial control environments with frequent use. Safety & Lockout Padlock Provision: Accepts up to three padlocks in the OFF position to secure the disconnect. Door Interlock: The handle mechanism includes a door interlock feature when in ON position, improving safety by restricting access unless the circuit is disconnected (this interlock can be overridden when needed for inspection). Typical Applications Manual isolation of power circuits via switch disconnectors in industrial panels. Operator actuation of load‑break switches and safety disconnects. Lockout/tagout procedures in maintenance and safety shutdowns. Electrical distribution gear and machinery panels where robust manual handles are required.
