I-Switch Stainless Steel Rotary Isolator – 40A 415V, Double Pole, IP66 Rated
This 40A double pole rotary isolator switch is housed in a premium Grade 304 stainless steel enclosure, providing high durability and resistance to corrosion in the harshest environments. Designed for both outdoor and hygiene-critical indoor applications—such as food processing, marine, and pharmaceutical facilities—the enclosure features a flush back and IP66 sealing. A safety interlock prevents cover removal when padlocked in the OFF position, ensuring secure maintenance and compliance with isolation procedures. The unit also supports auxiliary blocks and neutral assemblies for expanded functionality.
