In particular, the lead terminal connected to a vertical busbar is configured as a clip type with an increased contact contact, so that the current carrying capacity can be increased. The present invention relates to a motor control panel with reinforced current carrying performance.

일반적으로 공장이나 건물 등에는 상,하수도, 공기조화기, 펌프, 송풍기 등을 위하여 많은 전동기가 사용된다. 또한, 전열기, 조명장치 등에도 전원이 공급된다. In general, many electric motors are used in factories and buildings for water, sewage, air conditioners, pumps, and blowers. In addition, power is supplied to a heater, an illumination device and the like.

이들 전동기는 필요에 따라 자동으로 구동되거나 멈출 필요가 있으므로 전자개폐기를 사용하여 제어하고 있다.Since these motors need to be automatically driven or stopped as needed, they are controlled using an electronic switch.

이와 같이 다수의 전동기가 사용되는 경우에는 그 관리 및 운용의 편리성을 위해서, 여러 개의 전동기 유닛을 하나의 캐비닛에 집적한 형태의 전동기 전용 배전반을 사용한다.When a plurality of electric motors are used in this way, for convenience of management and operation, a motor-only switchboard of a type in which several motor units are integrated in one cabinet is used.

이러한 전동기 전용 배전반을 전동기 제어반, 동력반 또는 전동기 제어반(Motor Control Center ; MCC)라 한다.Such a motor switchboard is referred to as a motor control panel, a power panel, or a motor control center (MCC).

상기한 전동기 제어반은, 수직모선이 내설되어 있고, 상기 수직모선과 접촉 연결가능하도록 복수개의 인출단자를 갖는 인출 단자대가 유닛에 고정되어 단일체의 캐비닛에 내설가능하게 구비된다.The electric motor control panel is provided with a vertical bus bar, and a drawing terminal block having a plurality of drawing terminals so as to be in contact with the vertical bus bar is fixed to the unit and provided in a unitary cabinet.
