T279743S Single Phase 60 Hz 120/208/240/277 Primary Volts 120/240 Secondary VoltsAcme's single phase transformers are widely used to distribute power and voltage in both commercial and industrial applications. These transformers have been assembled using a state-of-the-art technology by highly knowledgeable and well-trained electricians. Acme stocks a full line of transformers that are built to the strictest European and UL electrical code of requirements.Conveniently, the quality of construction that is associated with T279743S Single Phase transformers makes them tolerant to the most extreme weather conditions. Therefore, no weather shields are required even to those that are mounted outdoors. All the required standards from OSHA, ANSI and NEMA have been adhered to if not surpassed.When purchasing a Single Phase transformer one should be aware of some specific factors. The most important issue is to establish the primary voltage and secondary voltage necessary for load equipment. Different transformers have different secondary and primary voltage capacity. The T279743S Single Phase transformer to be specific has a primary voltage of 120/208/240/277 and a secondary voltage 120/240. It is usually suggested that one should opt for a transformer which is larger than the actual load.Acme's transformers have a long and trouble free life.
