MNS Withdrawable LV Switchgear
Factory-built-assembly (FBA) modular switchboard on E=25 mm C-profiles — main busbar to 5000 A, 100 kA/1 s withstand; PC, MCC and auto power-factor cabinets in one standardised system.
- GB/T 7251.2-2023 — LV switchgear and controlgear assemblies
- IEC 60439-1:1999 — LV switchgear and controlgear assemblies
- JB/T 9661-1999 — LV withdrawable switchgear assemblies
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The MNS low-voltage withdrawable switchgear is a modular cabinet type factory-assembled (FBA) from standard modules. It suits power plants, substations, petrochemicals, metallurgy and steel rolling, transport and energy, light industry and textiles, as well as residential communities and high-rise buildings — for AC 50–60 Hz systems rated up to AC 660 V, for energy conversion, distribution and control. It complies with GB/T 7251.2-2023, IEC 60439.1 and JB/T 9661.
