■ lntroduction

P/PC series pressure control can protect compressors in refrigeration and air-condition plant, and keep them from over-low suction pressure or over-high discharge pressure.

P/PC series pressure controls can start and stop refrigeration compressors and fans of air condensers.

P/PC series pressure controls can be used not only in fluoride refrigeration, but also in air and liquid.

P/PC series pressure controls are fitted with 3 kinds of changeover switch: a single pole double throw (SPDT), a double pole single throw(DPDT) and a double pole double throw(DPDT). The position of the switch is determined by the pressure control setting and the pressure at the connector.

Approvals: CQC(China), CE(Europe), ROHS, UL(USA. Canada).
