KPU pressure control, failsafe (double bellows)
Type KPU16W Code no. 060-5251
KPU pressure controls are for use on commercial refrigeration and air conditioning systems to give protection against excessively low suction pressure or excessively high discharge pressure.
They are also used for starting and stopping refrigeration compressors and fans on air-cooled condensers.
KPU pressure controls are fitted with the Single-Pole Single-Throw (SPST) or Single-Pole Double-Throw (SPDT) switches, suitable for direct as well as indirect (with a contactor) control. KPU pressure controls are available in several pressure ranges and are compatible with non-aggressive, fluorinated refrigerants.
Standard enclosure is NEMA1.
