Data sheet

Pressure switch

Features

Approvals

Ship approvals

KP pressure switchs are for use in refrigeration

and air conditioning systems to give protection

against excessively low suction pressure or

excessively high discharge pressure.

KP pressure switches are also used for starting

and stopping refrigeration compressors and fans

on air-cooled condensers.

A KP pressure switch can be connected directly

to a single-phase AC motor of up to approx. 2 kW

or installed in the control circuit of DC motors

and large AC motors.

KP pressure switches are tted with a single-pole

double-throw (SPDT) switch. The position of

the switch is determined by the pressure switch

setting and the pressure at the connector.

KP pressure switches are available

in IP30, IP44 and IP55 enclosures.

• Ultra-short bounce time thanks to snap-action

function (reduces wear to a minimum

and increases reliability)

• Manual trip function (electrical contact

function can be tested without the use of

tools)

• Types KP 6, KP 7 and KP 17 with fail-safe double

bellows element

• Vibration and shock resistant

• Compact design

• Fully welded bellows element

• High reliability both electrically

andmechanically
