Application

This serial of protector can be used in the environment which is full of methane,dust and other explosive gas, in the current of 50Hz, voltage of 1140V or 660V non-ground electricity net, it can be used used as the main deliver switch, branch switch and also can be used as the infrequent start.

Features 

Adopting vacuum circuit breaker, long shelf life, big amount of short circuit breaking times,powerful arcing capacity ability. It is small in size and simple in structure.

This product is designed by module, reasonable layout,simple structure. Can be exchanged,easy to fix and use.

This ex-connecting circuit is designed of intrinsic-safe type, which makes it safer and more reliable.

This protector adopts advanced DSP micro processor and large capacity chips, high protection precision and fast response speed,equipped with power  leaking lock to prevent power leaking, under pressure,over pressure, unbalance of the three phases,over loading, short circuit, phase breaking, temperature protection, gas protection,wind and electricity locking down, valve opening and closing monitoring, vacuum cube monitoring function.

Equipped with fault-memory function.

Equipped with software and hardware self-test function, if any error occurs, the system will deliver the information accordingly.

All information will be displayed on the screen.

Adopting RS-485or CAN connector, the communication between monitor system and the units, equipped with four remote function, the real underground no guard can be realized.
