Why Choose the Lovato GEF0125F Switch Disconnector with Fuse Holder?
The Lovato GEF0125F is a three-pole 125 A switch disconnector with integrated NFC fuse holders, designed for dependable isolation, load switching and fused protection in industrial AC distribution systems. Part of Lovato Electric's compact GEF series, it combines switching and fuse-holder functions within a space-efficient panel-mounted assembly.
Rated at 125 A AC-21A, AC-22A and AC-23A at both 400 V and 500 V AC, the GEF0125F is suitable for demanding industrial loads. Its high 100 kA conditional short-circuit current, 1000 V insulation voltage and 8 kV impulse withstand voltage provide robust electrical characteristics for power distribution and machinery applications.
The GEF design incorporates transparent front windows to simplify fuse-status inspection and supports flexible vertical or horizontal installation. Direct-operating and door-coupled arrangements can be configured using compatible Lovato handles and shaft extensions, which are selected separately to suit the installation.
