JJZ1 type intermediate relay is electromagnetic DC control electrical appliances, suitable for internal combustion locomotives, electric locomotives and other industrial electrical automation control circuit equipment, used to control auxiliary circuits and other circuits of the automatic switching of electrical appliances, can be operated frequently, and can be controlled from a distance.
The product is characterized by flexible operation, reliable performance, small volume, light weight and long life. The electromagnetic control coil input is connected with over-voltage suppressor, which can absorb the over-voltage generated when the coil is disconnected from the power supply, and there is a light-emitting diode to show the action status. The auxiliary contact adopts JKW5 type quick-acting switch with IP60 protection level, which has the functions of quick-acting, self-cleaning, forced breaking, high reliability level, and sealed permanent magnet blowing arc.
