3 COMPETITIVE CHANGES A B THREE-PHASE, PLE MOTOR* Dual-voltage, -phase - V With plug-in speed selector coupled to operating voltage (see opposite). Built-in thermal overload probe protects winding at all speeds by external relay. New, more attractive terminal box. Electrical connections via stuffing box, input on right or left side. Display of rotation direction of motor, speed selected, and operating voltage. New data plate with information about all electrical values of the installed circulator. Very quiet motors. For -poles motors CN and CN ranges see the specific data sheets. THREE-PHASE MOTOR TERMINAL BOX Electrical connections easy to make, on very accessible terminal blocks. Speed selected by plug-in manual selector switch coupled to the operating voltage. Examples: A: speed - Voltage V B: speed - Voltage V The speed and operating voltage are displayed on the back of the terminal box. SINGLE-PHASE, PLE MOTOR V winding. Built-in capacitor.

ALTERNATING OPERATION PARALLEL OPERATION P P P + P PUMP OR PUMP IN OPERATION ONE HEAD ON STANDBY ENSURES OPERATING RELIABILITY WITH NO STOPPAGE OF THE INSTALLATION Operation of the pumps programmed and switched over by control box. Parallel operation of both heads for the flowrate required, allows substantially lower purchase and operating costs. A single head in operation provides about % of the capacity the installation needs during the heating season. The maximum hydraulic performance needed is delivered by parallel operation of both heads. A control box is used for programming.
