1. Product overview
XL distribution box full name is XL type low-voltage power distribution box. It adopts domestic self-designed components, compact structure, easy maintenance, and flexible combination of line schemes. In addition to air circuit breakers as short-circuit protection, the distribution box is also equipped with contactors and thermal relays, and the front door of the box can be equipped with operating buttons and indicator lights.
This equipment complies with the International Electrotechnical Commission IEC439-1 "Low voltage switchgear and control equipment device", China's GB7251-1997 "Low voltage switchgear and control equipment device", China's national standards and machinery industry association JB/T9661-1999 and CQC CCC national compulsory certification content.
2. Product use
XL series AC low-voltage distribution box is a three-phase four-wire or five-wire low-voltage distribution system with AC 50HZ, rated voltage of 380V or 660V for power distribution and lighting.
This equipment is suitable for power plants, substations, large buildings, high-rise buildings, airports, hospitals, theaters, stadiums, ports, underground facilities, industrial and mining enterprises, etc. XL type distribution box is used for power distribution in three-phase four-wire or three-phase five-wire system with AC voltage of 500 volts and below. XL type distribution box is installed against the wall of indoor installation, and maintenance in front of the screen.
XL type distribution box is closed, the shell is made of steel plate bending, knife fusion combination switch operation handle is in the upper part of the right column in front of the box, which can be used as a power switch. A voltmeter is installed in front of the distribution box to indicate the voltage of the bus bus. There is a door in front of the distribution box, and after the door is opened, all the equipment in the distribution box is exposed for easy maintenance and maintenance. This distribution box adopts domestic self-designed components, which has the characteristics of compact structure, convenient maintenance, and flexible combination of line schemes. In addition to air circuit breakers and fuses as short-circuit protection, the distribution box is also equipped with contactors and thermal relays, and the front door of the box can be equipped with operation buttons and indicator lights.
