Application

This series of vacuum switch is applicable in coal mine and the environment where the surrounding medium of mines has explosive mixed  gases such as methane, coal dust. In neutral non-grounding three-phase power grid system of AC 50Hz, voltage 6KV or 10KV, current 50-630A, together with our BXB series of low voltage protection box to protect and measure the mobile transformer substation.

Features

This series of products adopts vacuum circuit breaker( or permanent magnet mechanical, selectable for users) has main and sub circuit, electric switch, shunt trip, possessing the features of long service life and less maintenance, reliable operation, etc.

Adopting the LCD intelligent protector, featuring simple operation, wide application, high precision.

Full protection functions of checking the high temperature of overload, short circuit, under voltage, over voltage, transformer and various kinds of failure, remote supervision and control.

Self-check function: to ensure high pressure without fault operation.

Protection function：real-time monitoring the overload and over voltage.Once failure happens, cut off the failure circuit.

Memory function ：Long time to save the data and transport the record data

It has RS485 or CAN communication interface for the intrinsically safe type.
