Product Description

Product Introduction
The MNS AC low-voltage withdrawable switchgear is a modular, multifunctional low-voltage draw-out switchgear assembly. It is factory-assembled using standard modules and complies with IEC439-1 Low-voltage switchgear and controlgear assemblies and GB7251 Low-voltage switchgear and controlgear assemblies.
This equipment is suitable for AC 50~60Hz. It can be used as primary distribution equipment at the transformer side, as secondary distribution equipment at the load center, or as local distribution equipment at the load end. It is applicable to three-phase four-wire or three-phase five-wire power distribution systems with rated working voltage up to 660V and rated current up to 6300A. It serves as a low-voltage distribution device for power distribution, centralized motor control (MCC), and reactive power compensation in power generation and supply systems.
