Motor Control Center Equipped with Easy Operating Interlock Device

Motor control board of the present invention is configured to be installed in the interior of the enclosure includes a plurality of take-off unit that receives power from the bus bar to power the charge of the electric motor, and the maintenance work or if necessary take-off and drawn, the drawing unit, the first connector receives power from busbars and; And a second connector coupled to the power supply received from the first connector and the motor load; The power from the first connector to the second connector, or forward and keep the breaker body, the breaker switch to the circuit breaker body On / Off, the breaker switch to block when necessary or when an overload power to the breaker main body 4 breaker consists of a switch shaft gakba shape; The first connector, the second connector and the circuit-breaker is fixed is installed, it has a front plate and a left and right face plate and the rear plate and the bottom plate to which the circuit breaker switch take-button and the display of the instrument and the lamp device is installed, which is required during take-mouth sliding the box; The sliding also rides the guide rail installed on the floor, take-off, and pulling, with the unit holder is fixed to the housing of the electric motor control board; Inahut screw shaft and which is installed inside the sliding compartment to be pulled out the mouth with the rotation of the screw also the sliding; Coupled to the screw shaft and inahut operating handle for rotating the screw shaft inahut; The take-off unit is formed in the right portion is configured to include an interlock device for preventing the load is drawn out or drawn above also sliding in the jammed state, the interlock system is in a state off (Off) for the breaker switch rotunda consistent with the handle insertion hole and inserted into the handle and be able to rotate the inahut shaft screw, in the circuit breaker by the switch-on (on) state prevents the handle insertion hole and the circular hole is shifted to the left. According to the motor control board with the operation is easy interlock system of the present invention take-off unit, the take-mouth during a separate locking device opening of the circuit breaker by a link unit not installed in the circuit breaker operation may take a mechanical interlock required to secure or release of only a closing switching operation so to prevent the risk of erroneous operation due to a troublesome operation and can increase the ease and safety of operation, the device requires less rain.
