Certification for Seismic Testing

10 December 2022

LLC “Zavod KUB-Ukraine” declares that the XLG55 series cabinets, in combination with a steel sheet pedestal of 100mm or 200mm, already meet the requirements for seismic zones 1, 2, and 3 as standard. * For seismic zone 4, XLG55 cabinets can be equipped with an earthquake kit in combination with a comfortable handle and seismic-resistant pedestal, and they meet the parameters for an earthquake intensity of up to 9 points on the MSK-64 scale. Since empty (unfurnished) cabinet bodies cannot be certified, this should be considered as a comparative parameter.

Seismic Resistance




  • Object: Low-voltage distribution devices “Seismic-resistant distribution cabinets XLG55” (test object) Name: XLG55-2086 Cabinets (2000mmx800mmx600mm)
  • Construction type: Welded frame of steel frames.
  • Protection class: IP55, IK10, Un, B: 1000, In, A: 2500
  • Load, kg: 800
  • Supply set: frame with a ceiling panel, lockable doors, side and rear walls, solid bottom protection, seismic resistance kit with a 200mm pedestal, grounding kit, key, packaging.
  • Production: LLC Zavod KUB-Ukraine (UKRAINE)

The test results are satisfactory according to the program of tests for resistance to mechanical influences and seismic resistance. After each test, internal and external visual inspections were carried out. No damages or degradation were detected after each test. The purpose of the preliminary tests was to verify the cabinet body’s compliance with the requirements for resistance to mechanical influences (seismic resistance, vibration, impacts) stated in the regulatory documents (ND) Seismic test results.

Note: The vibration acceleration values correspond to the parameters of NP306.5.02/3.035-2000 for an earthquake intensity of 7 points on the MSK-64 scale and an installation height of the product up to 10 m.
