MWR FOURGROUP STARTER/CONTROL PANELS > ELECROMECHANICAL SOFT STARTER (AVSSE1) |
 |
General Description Electromechanical control panel with Soft-Starter for 1 three-phase deep well, submersible or surface pump, with adjustable thermal protection according to the power of the pump (see models). Start the panel by turning the door interlocking general switch, a blue light will indicate that the panel is operating. The pump starts when a float switch or a pressure switch closes the contact. The acceleration and deceleration ramps can be set up independently. The thermal overload protection is manually restorable. |
