Schneider Electric JCP803-007 Air Compressor Pressure Switch

The Schneider Electric JCP803-007 is a Square D air compressor pressure switch in the 9013FHG family, designed to regulate a compressor by turning the motor on at 135 psi and off at 175 psi within its 135–175 psi operating range. As a Pumptrol-style switch, it provides automatic control of the compressor circuit based on tank pressure, helping maintain steady air delivery and protect the pump from running without stored air. The JCP803-007 variant specifies a particular build within the 9013FHG lineup and is commonly used as a replacement part in Square D/Schneider Electric-compatible compressors that require a 135/175 psi control profile. This model is suitable for installations that rely on a fixed differential pressure to regulate cycling and maintain pressure within the target 135–175 psi window.
