Description

Feature

Parameter

The MLS low-voltage drawer type switchgear is a low-voltage switchgear that uses standard modules and is factory assembled (FBA). It is suitable for power distribution systems with AC 50 (60) Hz, rated working voltage ≤ 400V, rated working current 5000A and below, and is used for energy distribution, conversion, control, and reactive power compensation.
