UL-certified Series

In the USA, individual states and municipalities enact their own safety standards, and together with NFPA standards and NEC codes, many states and municipalities have adopted UL standards as safety-rating requirements that are more concretely embodied. Certification of compliance with UL standards earned a product a high evaluation for safety, and is also advantageous in terms of product liability. At Nunome Electric, our transformer and industrial control-panel operations have acquired UL certification, and we have achieved the creation of series for these products. We have also simultaneously received certification through UL for compliance with Canada's CSA standards.

How to read the Model Names

Required voltage combinations can be produced by means of the primary and secondary voltages indicated in the codes, but we recommend the standard specifications indicated in the dimension charts. When selecting a voltage combination not listed explicitly, the model name differs from the dimension chart.Please contact our Head Office Sales Division.
