HL series transformers are designed for applications where the possibility of a fire or explosion may result from sparks in environments containing high concentrations of dust, gases, or other volatile substances. The HL transformers wiring compartments are completely filled with electrical grade silica and resin leaving no access to the core and coil. The feature also minimizes air spaces where combustible particulates and gases may accumulate.
The enclosures are rated for NEMA 12 and range in size from .500kVA through 25kVA. Various voltage combinations are available.
