  • Gold Plated Elements - The STCE models ship with gold plated elements. These gold elements provide long life and superior scale resistance.
  • Glass-Lined Tank - Three sizes; 50, 80, and 119 gallon capacity. Tank interior is coated with glass specially developed for water heater use. Tanks rated at 150 psi (1034 kPa) working pressure (ASME 150 psi). Foam insulation reduces costly heat loss, and is vermin proof.
  • Fusing - Protects all elements, thermostats, and internal wiring circuits against excess current flow. Meets National Electrical Code requirements that non-ASME tanks must have internal fusing when current draw exceeds 48 amps.
  • Standard Voltages - 208, 240, and 480 V single-phase and three-phase delta. Convertible from three-phase to single-phase (in field) and vice versa. 277 V single-phase also available.
  • Terminal Block - Factory installed. Just bring the service to the heater and connect to block.
  • Controls - One temperature control (adjustable through a range of 120 to 180 ºF) and manual reset high temperature cut-off per element. Thermostat step control may be achieved by varying settings on individual temperature controls. Located behind hinged control compartment door for quick, easy access.
