Description
The Johnson Controls P100AP-4 Pressure Control Switch is a durable and product that has a dimension of 135 x 75 x 22 mm. This unit is constructed with die-cast aluminum to ensure long service and it can be mounted directly on panels or surfaces. Unlike the adjustable pressure switches, the P100AP-4 comes with a factory-set pressure setting for the specific pressure range. It has a cut-in pressure of 250 PSI and a cut-out pressure of 170 PSI, which makes it function like a switch. When system pressure reaches 250 psi (cut-in), the switch turns on, and equipment decreases pressure. On the other hand, when pressure gets to 170 psi (cut-out), the switch goes off, and stops equipment to avoid overcooling.
