Dungs Part Number: 248391

Special Order Item - 6- 8 Week Lead Time

Specifications

Dungs Minimum Pressure switch.

The control unit reacts on negative pressure, which connects, disconnects or switches a circuit when exceeding or falling below a set nominal value.

Simply acting pressure switch in negative pressure range. The G º pressure connection must not be closed.

The differential pressure acts on the micro switch via the membrane against the force of the adjusting spring. The pressure switch works without auxiliary power.

Mounting Orientation

	Standard Mounting Position
	The pressure switch is activated at a higher pressure when mounted horizontally: GGW 10 A4-U/2 X approx. + 0.05 kPa (0.5 mbar)
	The pressure switch is activated at a lower pressure if mounted horizontally overhead: GGW 10 A4-U/2 X approx. - 0.05 kPa (0.5 mbar)
