For your safety, it is crucial to purchase only genuine, ABB-manufactured electrical products (inclusive of those branded GE or GE by ABB and now manufactured by ABB). Counterfeit and non-authentic products may fail to meet safety standards, putting you at risk. To ensure you receive safe, reliable products, check the product description and photos and verify that the product is described as an ABB, GE, or GE by ABB product and has labels with an ABB, GE, or GE by ABB logo. Please also check the product description to see if the product has been certified by third-party certification bodies such as UL, IC and/or Intertek.ABB acquired GE's Industrial Solutions business in 2018 and continues to manufacture GE, GE by ABB, and ABB branded products under a license from GE.For warranty information, please contact the manufacturer's customer service directly. You may also be able to find warranty information on the manufacturer's website.
