PURPOSE:To prevent erroneous operation of an overload relay by fixing an electromagnetic contactor to a mounting frame through a mounting plate made of a damping steel plate. CONSTITUTION:An electromagnetic contactor T is fixed to a mounting frame 13a through a mounting plate 10. Because of this, the vibration due to the impact during opening or closing of the electromagnetic contactor 7 is absorbed by the mounting plate 10 made of a damping steel plate so that the vibration is not transmitted to the mounting frame 13a. By doing this, erroneous operation of an overload relay 8 fixed to the mounting frame 13a can be prevented. |
