Product Detailed
GHL AC LV Power Distribution Box is widely used in the power distribution system with AC frequency 50Hz.

GHL AC LV Power Distribution Box is widely used in the power distribution system with AC frequency of 50 Hz, rated insulated voltage of 500 V, rated operating voltage of AC 380 V/220 V and rated current no more than 630 A. It is an AC LV power distribution box for power supply, lighting, distribution, power switching and distribution control. Generally, it shall be installed near the powered equipment, such as pump house, fan house, elevator house, kitchen, electric shaft, functioning power distribution and control over those powered equipment. The power distribution box has both distribution and control functions. 


²       GHL AC LV Power Distribution Box is structured in framed fabrication, with flexible and convenient unit of various types.

²       It can be installed either single or side by side, with outgoing and incoming cables in such ways as up incoming up outgoing, up incoming down outgoing, down incoming down outgoing.

²       It has a fresh and graceful panel, with the door of 180° opening angle, freely open either from the front or the back, for the convenience of installation, commissioning, maintenance and operation.

²       Its main loop is full in scheme, besides those in common use, including dual-loop power incoming, connection, Y/D voltage-reduced start (to 55 KW), self-coupling voltage-reduced start (to 75 KW), reactive terminal compensation (to 60 Kvar).
