Description

Indoor electromagnetic lock is a kind of electrical control interlock device to prevent the operation of Medium Voltage electrical switchgear with electricity, it is generally used in combination with Medium Voltage charged display device, mainly for Medium Voltage complete switchgear, box change, isolation switch, circuit breaker and other electrical equipment. When the Medium Voltage charged electromagnetic lock can not be opened (equal to the equipment door can not be opened) will not occur when the Medium Voltage charged misoperation, when the Medium Voltage is not charged, the external power supply is connected, the control electromagnetic lock can be opened. This effectively prevents the Medium Voltage charged misoperation, ensures personal safety, and effectively extends the life of the electromagnetic lock itself.
