Interior And Outdoor Floor Type XL-21 Power Distribution Cabinet​

Product overview
　　

The XL low-voltage distribution device (hereinafter referred to as the device) is suitable for the power distribution system with AC 50Hz and rated voltage of 0.4KV and less. The device, which integrates power distribution, metering, reactive power compensation, protection and reclosing, has the advantages of high protection level, perfect protection performance and high automation degree, and is the ideal preferred product for power grid transformation.　　

The product meets IEC439< low voltage switchgear and control gear GB7251-97< low voltage switchgear and other standards.

Principle of operation

Device metering with DD862 single phase meter or DT862 three-phase four wire electrometer and class 0.5 current transformer, CJ20 AC contactor as total power control; distribution distribution with DZ20Y-100 plastic shell circuit breaker; new type JD6 silent operation leakage relay control CJ20 AC contactor effectively for leakage and electric shock protection; JKG2C reactive power controller monitor and automatically cut BSJM self-healing low voltage parallel capacitor for reactive compensation.
