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.

  • Double Pole Isolation: Safely disconnects both live conductors in single-phase 415V systems—ideal for motors, machinery, and plant equipment.
  • Robust Stainless Steel Enclosure: Made from 1.2mm thick Grade 304 stainless steel for long-term performance in aggressive or washdown environments.
  • IP66 Rated Protection: Fully sealed against dust and high-pressure water jets—perfect for indoor or outdoor industrial use.
  • Padlockable OFF Position: Ensures secure isolation by preventing cover removal when locked out, supporting safe maintenance practices.
  • Auxiliary-Ready Design: Base-mounted disconnector supports optional auxiliary contacts and neutral terminals for greater flexibility.
  • Complete Earthing: Earth continuity terminals included in both the base and lid for full system safety.
  • Cable Access: 2 x M20 cable entries (top and bottom) for convenient wiring.
