Pressostato bipolare 4 vie

High-performance pressure switch for AC voltage for compressors / for pumps

Pressure connector material = die-cast aluminium.

Motor switching capacity 2.2 kW.

Max. cut-out pressure 11 bar.

2-pole (NC)

The MDR-2 pressure switch is fitted as standard with the possibility for pressure difference adjustment. Two adjusting screws permit switching point and hysteresis to be adjusted, whereby the cut-out point is first adjusted via the main pressure spring and then the cut-in point via the pressure difference setting. By selecting a pair of values for cut-in and cut-out pressures, an intersection point is determined in the diagram. If the point lies within the shaded area, this pair of values can be adjusted on the pressure switch. If the point lies outside the shaded area, this pair of values cannot be adjusted on the pressure switch.
