Compact switchgear. Complete peace of mind
GMA is Schneider Electric’s 24 kV gas-insulated switchgear built for safe distribution, compact footprint, and dependable performance across feeders, risers, couplers, and fuse-switch bays
Explore MoreHeat. Loose joints. Ageing mechanisms. Big downtime risks
Older MV panels hide insulation wear, miss early heating, drift in interlocks, and lose pressure over time. That leads to unsafe switching, unexplained trips, and unpredictable outages.
Meet GMA — compact GIS built for tough MV networks
GMA is a factory-assembled, SF₆-insulated medium-voltage switchgear platform rated up to 24 kV and 2500 A, with 31.5 kA breaking capacity. It comes in multiple cubicles — breaker, bus coupler, fuse-switch, and bus-riser — each engineered for smooth operation, clear interlocks, and long-life performance. From connection tightening to SF₆ health, mechanism checks to relay upkeep, GMA stays reliable through OEM-guided maintenance and strong mechanical design. It’s compact. Safe. Durable. And ready for dense substations and industrial loads.
