The power distribution cabinet is the general name of the motor control center.
Power distribution cabinet is a device that is intended to provide supply and redistribution of electrical energy, protection of electrical power lines and protection of the overload and short circuit currents. In addition, system allows measuring of energy consumption when equipped with power meters.
GBL- -21 series power distribution cabinet is suitable for power plant and industrial and mining enterprises, three-phase three-wire, phase four-wire, three-phase five-wire system with AC voltage of 55 0V and below for power lighting distribution. GBL--21 power distribution box is an indoor device, installed on the wall, and screened for maintenance.

■Normal use conditions

Ambient temperature: -5 °C ~ +40C, and the average temperature within 24h does not exceed +35%C. Altitude: no more than 2000m. Relative humidity: no more than 50% when the ambient air temperature is +40 °C; higher relative humidity at lower temperatures (eg 90% at +20 °C), allowing for changes in temperature Produces moderate condensation. The vertical inclination of the equipment should not exceed 5 degrees. Equipment should be installed in locations where there is no violent vibration, no impact, and no corrosion.
The GBL type low-volta

■Structural characteristics

ge power distribution cabinet is installed indoors against the wall, and the power distribution device with a single front opening is made of steel plate bending and angle steel welding.
