Schneider KP1E Pressure Switch for Industrial Fluid Control

The Schneider KP1E monitors pressure levels in hydraulic and pneumatic systems. You can mount this device directly onto a pipe or manifold using standard fittings. It activates or deactivates a circuit when pressure reaches a setpoint. This switch suits lubrication, cooling, and safety interlock applications.

Technical Specifications and Physical Construction

The Schneider KP1E measures 85 mm in height. Its width reaches 55 mm, and the depth equals 45 mm. The Schneider KP1E weighs approximately 0.22 kilograms. A single internal SPDT micro-switch provides the electrical contact. The unit contains no energy storage capacitors or batteries. One 1/4-inch NPT male thread connects to the pressure source. Three screw terminals accept the electrical wiring connections. A transparent plastic cover protects the adjustment mechanism.

Pressure and Electrical Ratings

The Schneider KP1E covers an adjustable range from 1 to 10 bar. Maximum working pressure reaches 15 bar without damage. The SPDT contact switches 5 A at 250 V AC resistive load. A visible red indicator shows the current contact status. Consequently, this switch provides reliable on-off control for pumps and valves. The differential gap adjusts from 0.5 to 1.5 bar for precision control. The diaphragm-style sensor works with air, oil, and water media.

Installation and Adjustment Guidelines

You must mount the Schneider KP1E vertically to prevent moisture ingress. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. A 19 mm hex wrench secures the connection to the pressure port. Adjust the setpoint using the internal spring screw under the cover. The operating temperature range spans from -25°C to +85°C reliably. IP54 protection rating resists dust and splashing water.
