P Series Pressure Control Pressure Switch
Descriptions:
1. P pressure controls are for use in refrigeration and air conditioning systems to give protection
against excessively low suction pressure or excessively high discharge pressure.
2. P pressure controls are also used for starting and stopping refrigeration compressors and fans
on air-cooled condensers.
3. P pressure controls are fitted with a single-pole double-throw (SPDT) switch. The position of the
Switch is determined by the pressure control setting and the pressure at the connector.
