XL-21 low voltage power distribution cabinet

XL-21 low voltage power distribution cabinet
Product Description
XL-21 low-voltage power distribution cabinet is a new type of domestically
designed components for BOKR Electric.
The shell is made of steel plate, with compact structure, convenient
maintenance, and flexible circuit scheme Combination and other characteristics;
in addition to the installation of air circuit breakers and fuses as circuit
breaker protection.Equipped with contactors and thermal relays, the front door
of the box can be equipped with operation buttons and indicators, and a knife
switch is required.
At the time, the knife switch operating handle is installed on the upper right
column of the front of the box, which can be used to switch the power supply
and power distribution.
There is a door in the front of the box. After the door is opened, all the
equipment in the distribution box is exposed for easy maintenance.
XL type Power distribution cabinets are used in industrial and mining
enterprises, civil buildings, schools and institutions, and exchange frequency.
Single-phase and three-phase, 50Hz ^ 60Hz, load current below 630A, IT system
below 500V, TN-C system, TT system (formerly known as three-phase three-wire,
three-phase four-wire power system) for power and lighting For power
distribution.
Low Voltage Switchgear Working environment:
1.Ambient temperature: -5 ℃ ~ + 40 ℃, and the average temperature within
24h not exceed + 35 ℃.
2.Altitude: not exceed 2000m.
3.The ambient air temperature of + 40 ℃ not more than 50%; at lower
temperatures can have a higher relative humidity on (eg: + 20 ℃
at 90%), taking into account the change in temperature allows the generation of
a moderate condensation.
4.Equipment installation and the vertical gradient should not exceed 5 °
5.Equipment should be installed in the absence of severe vibration, shock-free
and corrosion-free place
