1. General   TXL-21 LV power distribution low voltage switchgear is suitable for the power plant, industrial and mining enterprises, to distribute the power distribution in the AC 500V and below three-phase four-wire or three-phase five-wire system. TXL-21 LV power distribution low voltage switchgear can be only mounted against the wall in the building. The shell of low voltage switchgear is made of the bending steel plate; the knife switch operation handle is on the top of the right column to transfer the power. There are various kinds of circuit breaker for the users.       3. Technical parameters
