This is the KP1 pressure switch. It has a wide adjustable range, with the pressure (Pe) adjustable from -0.2 bar to 7.5 bar. This feature allows it to be applied in various scenarios where different pressure settings are required.
The maximum working pressure of this pressure switch is 17 bar. This parameter determines its applicable pressure range during normal operation, ensuring stable performance under high - pressure conditions within this limit.
Regarding its protection level, it reaches IP44. This means it has a certain degree of protection against solid objects and splashing water. It can be used in relatively harsh environments without being easily damaged by external factors, which effectively extends the service life of the product.
The pressure connection type is flare, and the connection size is 1/4. The pressure connection uses external threads, which is convenient for installation and connection with other pipelines. The pressure sensing element is a bellows, which is sensitive to pressure changes and can accurately transmit and respond to pressure signals.
In terms of electrical performance, it has multiple contact functions. The contact function is SPDT (Single Pole Double Throw), which can meet different circuit connection requirements. The contact capacity is also diverse. For example, for AC15, it is 10 A at 400 V; for AC1, it is 16 A at 400 V; for AC3, it is 16 A at 400 V; for DC13, it is 12 W at 220 V; and for LR, it is 112 A at 400 V. These electrical parameters ensure its compatibility and stability in different electrical systems.
The product is compliant with multiple certifications, including CE, China RoHS, EU RoHS, UK RoHS, and UL. It is also approved by BV, CCC, DNV, GL, LR, LVD, PED, PZH, RINA, RMRS, etc. This indicates that the product meets strict international and domestic standards in terms of safety, environmental protection, and quality, providing users with reliable guarantees.
The product can be used with a variety of refrigerants, such as R113, R124, R134a, etc. It is also suitable for no - oil applications, showing good lubricant compatibility. The environmental temperature range for use is from -25 °C (-13 °F) to 65 °C (149 °F), and it can withstand a maximum temperature of 80 °C (176 °F) for 120 minutes, making it adaptable to different environmental conditions.
The packaging method is multi - packaging, with 36 pieces per package, which is convenient for storage and transportation. Additionally, there are various documents available, including product manuals, installation guides, and data sheets in both Chinese and English, providing users with comprehensive product information and technical support for installation and use.
