Power (lighting) distribution cabinet
summary
XL-21 low-voltage power distribution cabinet (box) is suitable for use in factories and mining enterprises such as metallurgy, mining, petroleum, chemical, textile, ports, and stations. It is used for power distribution and lighting in three-phase three wire, four wire, or five wire low-voltage distribution systems with AC 50Hz, rated voltage of 400v or 66v, and rated current value of 630A. It can also be used for controlling some squirrel cage and attack type motors in low-voltage control systems.
This product complies with standards such as IEC60439-1:1992 and GB7251 • 3-2006 "Low Voltage Switchgear and Control Equipment".
Normal environmental conditions for use
Temperatura ambienta non est alta quam+40C aut inferiora quam -5C, et mediam temperaturam inter 24 horas non est alta quam+35.
Weather conditions, clean air and relative humidity not exceeding 50% at a maximum temperature of+40C. Higher relative humidity is allowed at lower temperatures, such as 90% at+20 ° C, but consideration should be given to the possibility of occasional moderate condensation due to temperature changes. Altitudo non excedet 2000 metros.
This product is suitable for transportation and storage at temperatures ranging from -25C to+55C, and can reach+70C in a short period of time (not exceeding 24 hours). At these extreme temperatures, the device should not suffer any irreparable damage and should be able to function normally under normal conditions.
Si supra conditiones utilizae non potest occurrere, usator opus cum fabricatore ad ordinem et negotiationem solutionem elevabit.
Productibus Features
The XL-21 power distribution box is divided into two types, the ordinary type (P-type) with a box height of 1700mm and 1800mm. The box is installed independently and can have inlet and outlet holes on the top according to requirements; Custa altitudinis 1900mm ex M-typo est cum summo busbar, et summo cista tecta est placuis detachabile pro facile installatione et auferentia busbar.
Raeda cisternae ex acido facta est, et ianuae, latera et rea plateae significabile sunt. Installationes et trabes latera adjustabile sunt, et instauratio et observatio flexibile, convenibile, compactile et versatile sunt. Adopting precision cast adjustable hinges, the opening of the door is greater than 135°. Cortina installationis intra cista in totum postquam constituentur componentes. Est instabilis et introibitur et exire secundum universas environamentibus utilizationis, cum versatibilitate forte et in combination cum universibus pluribus utilizatur.
