BBL-1140
Mine-used explosion-proof long-distance terminal protector
Purpose and scope of use Application and range of application
This product is suitable for use in coal mine underground and the environment where the surrounding medium contains explosive gases (methane mixture). It can be used in the power grid with an alternating current of 50HZ and a voltage below 1140V, serving as a long-distance short-circuit protection function.
Product features Product features
This product's short-circuit protection does not use current sampling and is not affected by cable length, area, and current. Within the allowable voltage drop range, the protection distance can be extended arbitrarily;
When the terminal protector is connected to the farthest end of the power supply distance of the comprehensive lighting protection device, it can achieve long-distance short-circuit protection for any two-phase and three-phase circuits.
