QBZ-30, 60, 60N mining flame-proof reversible electromagnetic starter
Applied in mine full of explosive gas such as methane, in circuit of 380/66V, rated current up to 60A.
Application
This series starter can be used in coal mine and other places full of explosive gas mixture such as methane, coal-dust, and so on. It can directly or remotely control mining flame-proof three-phase asynchronous mouse-cage liked motor for start and stop positively and negatively, also can change phase when controlled motor stops in the circuit of AC 50Hz, rated volate 660V or 380V, rated current up to 60A.
Feathres
1. Main circuit uses vacuum contactor, no electrical arc, with long service life and sceurity.
2. Use JDB electrical machnine comprehensive protector, with complete protection function.
3. Reliable electric inter locking and machniery inter locking exists between two contactor wich connect in direct-reverse way.
4. Simple structre, less maintenance.
