XL-21(G) Low Voltage Power Panel

Overview

XL-21(G)x LV closed type power panel can be used in AC 500V or lower system of three-phase three-wire, three-phase four-wire, three-phase five-wire for electricity-generating and mine enterprises, also for the purpose of power, lighting, distribution. XL-21(G) type low voltage power panel has flexible distribution scheme, convenient combination, good practical performance, new structure and etc.

STRUCTURE FEATURE

1.Main electrical performance shall completely comply with regulations of IEC60439-1:1992,GB7251.1-1997.

2.The auxiliary circuit has functions of local/remote, remote, automatic control and in-site/remote, remote control switch. The contactor can adopt DC protection.

3.Receiving main switch has optional protection of instant trip and pyromagnetic trip. Can cancel instant protection for matching next class main-switch, avoid skip-class tripping, and has functions of motor/manual operation and automatic switch.

4.Main switch of feeding circuit has protection of instant trip and pyromagnetic trip. Can add fault protection if customer required.

5.The motor control circuit has protection of short-circuit instant, overload, undervoltage release and phase-break.

6.Ammeter and voltage meter for incoming circuit.
