HZ Series industrial control transformers are designed for applications where cost or heat issues make mounting the transformer outside the control panel necessary. This encapsulated transformer has copper windings for industrial applications. The UL Class +180°C insulation system allows for a +80°C temperature rise under full load. Standard models are UL Listed/NEMA Type 3R (rain proof); however custom models are available for UL Listed/NEMA Type 4, 4X and 12 requirements.
