I-Switch Stainless Steel Rotary Isolator – 25A 415V, Double Pole, IP66 Rated
This 25A double pole rotary isolator switch is housed in a robust Grade 304 stainless steel enclosure, making it ideal for use in extreme environments—indoors or out. With full IP66 sealing, this isolator is engineered for locations exposed to weather, high humidity, or aggressive cleaning processes such as food production, marine, or pharmaceutical settings. It features a safety interlock that prevents cover removal when padlocked in the OFF position and accepts auxiliary blocks and neutral assemblies for added flexibility.
- Double Pole Isolation: Suitable for single-phase 415V loads requiring safe disconnection of both live conductors.
- Grade 304 Stainless Steel Enclosure: 1.2mm thick with flush back surface—resists corrosion, impact, and harsh cleaning agents.
- IP66 Protection: Fully sealed against dust and powerful water jets, ideal for outdoor or hygienic indoor environments.
- Padlockable Safety Feature: Prevents cover removal when locked in OFF position—supports safe lockout/tagout compliance.
- Auxiliary Ready: Base-mounted disconnector accepts optional auxiliary contact blocks and neutral assemblies.
- Earthing Points: Earth continuity terminals provided in both the base and lid for complete safety compliance.
- Cable Entries: 2 x M20 pre-formed entries for quick, standardised installation.
