water. Element sizes from 1.5 to 6 KW. Maximum input 12 KW (see chart on back).
120, 277 single phase and 208, 240 and 480V unbalanced three-phase delta; easily converted to single-phase at terminal block (except 208V with 6000 watt elements). Single element heater, single-phase only.
Factory-installed. Just bring the service to heater and connect to block. Terminal block not supplied on 120V & 277 volt models. ( No junction box on
