[hunan Chuang'an Explosion-proof] Zjz-□/□ml Mine-used Flameproof and Intrinsically Safe Lighting and Signal Comprehensive Protection Device (quick Connection)

ZJZ-Port/PortML

Mine-used flameproof and intrinsically safe integrated protection device for lighting and signal (Quick connection)

Purpose and scope of use Application and range of application

This series of flameproof and intrinsically safe integrated protection devices for lighting and signal are suitable for coal mines underground, in the power grid of alternating current 50Hz, rated voltage 380V, 660V, 1140V. It is a new high-performance series of microcomputer-controlled protection products with high power supply reliability; multiple anti-interference measures are adopted to make the device have extremely high anti-interference ability. It is used for the power supply of 127V lighting and signal loads in coal mines underground.127V lighting and signal loads for power supplyElectricity, and at the same time, it has protection functions such as short - circuit and leakage.

Product featuresProduct features
