JK17-125 AC limit switch
Product Introduction
The JK17 – 125 AC limit switch is primarily used in the power supply circuit of construction hoists with an alternating current frequency of 50Hz, a rated operating voltage of up to 380V, and a rated operating current of up to 125A. When the limit switch of the hoist malfunctions, this switch can be used to cut off the main power supply of the hoist, thereby providing terminal limit protection for the construction hoist.
The housing components of this product are formed through aluminum alloy die – casting. It is both aesthetically pleasing and robust, boasting good mechanical strength. The internal contact – cam combination is precise, fully meeting the requirements for the terminal limit protection of construction hoists.
