Product Description Specifications Pressure Switch can protect compressors in refrigeration,and keep them from over-low pressure or over-high suction pressure.

Features: 1)Air compressor pressure switch can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure. 2)Air compressor pressure switch can start and stop refrigeration compressors and fans of air condensers. 3)Air compressor pressure switch can be used not only in fluoride refrigeration, but also in air and liquid. 4)Air compressor pressure switch are fitted with a single pole double throw (SPDT) changeover switch. The position of the switch is determined by the pressure control setting and the pressure at the connector. 5)Approvals: DnV, Det norske Veritas (Norway), CQC (China), CE (Europe). Technical data:
