XL Low voltage switch cabinet
XL low voltage switchgear is suitable for the distribution system of AC 50HZ, rated voltage 380V, rated current to 630A three-phase three wire, three-phase four wire, three-phase five wire system. It is used as power and lighting equipment, and at the same time, it is also controlled by motor in low voltage control system. XL low voltage switchgear conforms to IEC439 "low voltage switchgear and control equipment", GB7251 "low voltage switchgear" and other standards.
◇Main Features：
XL low voltage switchgear is generally a floor type structure. The basic structure is made of steel plate bending and angle steel welding. The door can be equipped with operation buttons, indicator lights and display instruments. According to the type, specification and quantity of the components, all kinds of distribution boxes with various control functions can be designed. The size of the box has a wide selection range, making the structure a perfect combination, convenient combination and strong applicability. Both the door and the shell contain earthing screws to ensure that the shell is connected to the ground reliably. The operation is safe and easy to maintain。
