Model and meaning:
structure characteristics
The XL type low-voltage power distribution cabinet is enclosed, with a shell made of bent steelplates. The knife switch operating handle is installed on the upper right column in front of the boxand can be used to switch power sources. There is a voltmeter installed in front of the distributionbox to indicate the voltage of the busbar. There is a door in front of the distribution box. Whenthe door is opened, all equipment inside the distribution box is exposed for easy maintenanceand repair. This distribution box adopts domestically designed components, which have thecharacteristics of compact structure, easy maintenance, and flexible combination of circuit schemes.In addition to air circuit breakers and fuses for short-circuit protection, the distribution box is alsoequipped with contactors and thermal relays. The front door of the box can be equipped withoperation buttons and indicator lights.
Conditions of Use
◇Environmental temperature: -50 °C ~+40 'C , and the average temperature within 24 hours doesnot exceed+36 °C ;
◇Altitude: not exceeding 2000m;
◇Relative humidity: not exceeding, 50% when the surrounding air humidity is+40 °C ;
◇ Under lower humidity conditions, there can be higher relative humidity (such as 90% at+20 °C ),allowing for moderate frost formation due to temperature changes;
◇ The inclination angle between the equipment and the vertical plane should not exceed 5 ° duringinstallation, and the equipment should be installed in a place without severe vibration, impact, andcorrosion.
