Single Phase Dry-Type Low Voltage Distribution Transformers

Advantages Compare our standard series of single-phase distribution transformers to other brands on the market. Pays for itself quickly in energy savings. Efficiency well exceeds the guidelines of NEMA's new Premium Efficiency Transformer Program.   40 to 50% reduction in volume. Weighs 40% less, generating considerable savings in transport and installation costs. Temperature rise at full load is less than 80 C (176 F) allowing use of non-ventilated enclosures. The inherently quiet operation of the toroidal transformers inside the low profile enclosures make Bridgeport Magnetics distribution transformers well suited for interior baseboard installation. Where floor space is at premium cost, the Bridgeport Magnetics distribution transformer enclosures can be easily wall mounted vertically or horizontally. Dry-type single-phase low voltage (<600VAC) distribution transformers suitable for industrial, healthcare, commercial buildings, shopping malls, schools, theaters, churches and libraries and other applications. Enclosures Mounted inside of sleek rectangular green epoxy powder coated steel enclosures. Wire termination is with screw-type terminal blocks. Stud-type connectors are optional.  The enclosures have a water tight, hinged, locking door.
