137 SWITCHES PRESSURE CB SWITCHMATIC 2T is a three-phase electronic pressure switch with integrated digital manometer. It manages the start and stop of a three-phase pump up to 4kW (5,5 HP). Cut-in and cut-out pressures are easily adjustable through the user friendly control panel. CB SWITCHMATIC 2T includes instantaneous current and voltage readings. It can be mounted individually or in groups of 2 pumps synchronized and operating in cascade mode with alternated operation sequences. This patented version controls and manages the overcurrent, voltage out of range protection, the dryrunning protection of the pump and fast cycling protection.
