    Each internal power circuit is fused for safety. Each power circuit to an immersion element is fused at a maximum of 48 amps. Power circuits may be fused at lower current levels as needed to balance current on three phase units. The power circuit fuses are held by a spring loaded fuse block rated fo...

    This water heater uses an immersion thermostat(s) to activate magnetic contactors allowing current to flow to the immersion heating elements. The standard control system uses one immersion thermostat for each 54kw of electric heating power in a water heater. As an option, additional immersion thermo...
