Mine Lighting Apparatus AOSH-0.25...10.0 for Efficient and Safe Lighting

Apparatuses lighting mine type AOSH-0,25 ... AOSH-5,0 are designed to supply lighting networks, signalling circuits and other electrical receptors with voltage 36V, 127V and 220V in mines, mines and other enterprises not dangerous for gas and dust explosion. The devices are used in three-phase AC networks with insulated transformer neutral voltage 1140, 660V or 380V, frequency 50 Hz. The devices with output voltage 220V and 127V have built-in leakage relays.
