The Saginomiya SNS-C130PKQ is a high-quality dual pressure control switch designed for use in refrigeration and air conditioning systems. It combines both low-pressure and high-pressure control functions into a single, compact unit. This device is essential for protecting refrigeration compressors by preventing operation at excessively low suction pressures or dangerously high discharge pressures. The SNS-C130PKQ features an automatic reset on the low-pressure side and a manual reset on the high-pressure side, providing an added layer of safety by requiring manual intervention after a high-pressure fault. Its robust construction and reliable performance make it a trusted choice for commercial and industrial refrigeration applications.
