Isolation Transformer defined: A transformer which isolates the primary circuit from the secondary circuit. An Isolation/distribution type Transformer should be used on all systems that require grounding of the load. Single Phase isolation/distribution type transformers are ideal for supplying auxiliary lighting circuits from 600V and lower supplies and electric heating equipment.

Features

• General purpose indoor ventilated steel enclosure (Nema-1 or CSA-1) suitable for dry locations. After fabrication, the enclosure is finished in ASA61 grey powder paint suitable for most industrial and commercial installations.
• Transformers up to 75KVA may be readily hung on H-columns, walls, shelves or floor mounted to suite each typical installation. Most units have lifting lugs, conduit knockouts and removable front and back covers for easy access to terminals.
• Transformers larger than 75KVA are suitable for floor or platform mounting only.
• Transformer terminations rated below 330A are supplied with suitable hardware and lugs for cable connection. Terminations above 330A are supplied with termination pads.
  • Class 220 Insulation
  • 150^OC Temperature Rise
  • Primary Taps ±2½% & ±5% (±5% only on 5KVA-15KVA)
  • CSA certified, File No. LR34493
  • UL Listed, File No. E108255
  • ISO9001 Quality Certification
  • Available in Copper (Cu) or Aluminum (Al) windings
