It is used for machine tools.
I turn on / off the motor of 400W and 60W about 500 times each day.
We believe that the lifetime is 2 to 3 years consumable items.
Although it looks refreshed with a terminal cover with a model change,
It becomes an obstacle when two or three wires are connected to a terminal in a narrow power supply box.
Since the thing which was attached before was a waste version, wiring placement position was different from before but it was able to be used without problems. If the number of wiring is large, you can not install the cover.
No placement of NO contacts between # 13 and # 14 is considered. We have created a switch box that controls ON / OFF of the motor with the minimum configuration of this thermal, A contact S / W, B contact S / W. In the case of the thermal around S-N 20, the contacts of 13 - 14 were arranged in the lower right hand stage, but in S - T 20 it is located on the left side, remove the thermal relay once, wire it to 14 It is necessary to connect the thermal. Although it is troublesome to create newly, wiring is expected to become extremely difficult when it is necessary to change the wiring in the condition incorporated in the control panel. Since there are no B contacts besides 21-22, is this arranged?
