K20E2H112S - SolaHD 112.5KVA 480D-208Y K-20 RATED


K-Factor transformers are designed to reduce the heating effects of harmonic currents created by loads like those shown in the chart below. The K-Factor rating is an index of the transformer's ability to withstand harmonic content while operating within the temperature limits of its insulating system. K-Factor transformers have UL ratings of K-4, K-13 and K-20.

These specialized transformers feature conductors capable of carrying the harmonic currents of non-linear loads without exceeding the temperature rating of the insulation system. The basic design takes into account the increase in naturally occurring "stray" losses caused by non-linear loads that can cause standard transformers to dramatically overheat and fail prematurely. The core and coil design manages the DC flux caused by triplen harmonics that can cause core saturation, voltage instability and overheating in a standard transformer.

Features
  • Conductors carry the harmonics of a K-rated load without exceeding insulation temperature ratings
  • UL 1561 Listed up to K-20 rated protection
  • Rated temperature rise of 150°C/302°F, 220°C/428°F insulation
  • Shielded for quality power
  • Basic design takes "stray losses" into account, functioning within safe operating temperatures
  • Core and coil design is engineered to manage the zero sequence flux caused by triplen harmonics
  • Provides 100% rated current without overheating the windings or saturating the core
  • Accessories and Optional Design Styles
  • Wall mounting brackets (item WB1C, 500 lbs. maximum)
  • Weather shields (UL-3R, order separately)
  • Totally enclosed, non-ventilated designs (TENV, non-UL)
