AIS-3: One Switch Way, 15 kV / 25 kV, 600 A, Adaptable

Streamlined Single Switch Operation: The AIS-3 PME type air-insulated switchgear is engineered for systems needing a single switch way, available in both 15 kV and 25 kV configurations with 600 A deadbreak bushings. The AIS-3 model provides an efficient power distribution solution, featuring a dead-front design housed in a mild steel cabinet with an optional stainless steel upgrade for enhanced durability. Each bushing is adaptable to universal 200 A loadbreak bushing wells, offering increased flexibility.

  • Air-Insulated Dead-Front Design: Enhances safety by minimizing electrical exposure and reducing maintenance and outages from vegetation or animal interference.
  • Louvered Enclosure Design: Prevents unwanted gases and moisture from building up inside the enclosure.
  • Strength and Durability: 11-gauge mild steel construction, and option to upgrade to 304-stainless steel for enhanced robustness.
  • Maximum Visibility: 600 A switch position and fuse condition through large viewing windows.
  • Built-in Base Spacing: Increases door clearance and reduces the need for additional base spacers.
  • No center door support: Increases working area in cable compartments.
  • Field-Replaceable Switch-Way Bushings: (200 A or 600 A), ensuring flexibility and convenience.
  • Internal No-Drip Compound: No-drip compound that prevents moisture condensation under the roof.
  • Fault Indicator Window: for easy mounting and viewing of common fault indicators.

The Hubbell A.B. Chance AIS-3 PME type air-insulated switchgear offers a pad-mounted, single switch solution with a dead-front design, adaptable 600 A deadbreak bushings, and durable construction for efficient power distribution in various settings. The specifications listed in Product Details below are presented as two sets of values for each voltage class model: 15kV / 25kV.
