VUOTOTECNICA DO10094

The need to use the same vacuum pump in various spots in the work environment,such as, for example, a shipyard, has led us to creating this mobile switchgear that allows for polarity reversal in presence of current, as well as for time setting pump operation and the automatic start-up restoration in case of accidental black-out. The switchgear is enclosed in a special watertight metal casing and it is composed of fuses, remote control switches with thermal protection and a transformer for low voltage auxiliary command power supply. The following are instead installed on the casing lid: - A line switch with indicator light - A changeover switch for pump start-up with indicator light - A changeover switch for polarity reversal - An emergency button - A timer for setting the duration of pump operation - An hour-counter for counting the actual pump operation time - A malfunction warning light. This switchgear is supplied in special metal watertight casing and can manage pumps with power up to 7.5 Kw.
