The Lovato GEF0125FT4 is a four-pole 125 A switch disconnector with integrated NFC fuse holders, designed to combine manual electrical isolation and fuse accommodation in a compact industrial switching assembly. Part of the Lovato GEF series, it is suitable for AC power distribution, switchboards, machinery and industrial control-panel applications.
Rated at 125 A AC-21A, AC-22A and AC-23A at both 400 V and 500 V AC, the GEF0125FT4 provides robust switching performance for demanding loads. It also offers a high 100 kA conditional short-circuit current, 1000 V rated insulation voltage and 8 kV impulse withstand voltage.
The four-pole configuration allows simultaneous switching of four conductors, making the GEF0125FT4 particularly useful where the neutral conductor also needs to be switched. The unit uses NFC fuse holders and is designed for screw-on-plate installation, with compatible Lovato operating handles and other accessories available to configure the switching arrangement.
The Lovato GEF0125FT4 combines load isolation and fuse accommodation within a single coordinated device, reducing the number of separate components required in industrial power-distribution assemblies. Its four-pole configuration provides a practical solution for circuits where all three phases and the neutral conductor need to be switched together.
With 125 A AC-23A switching capability, a 100 kA conditional short-circuit current and an 8,000-cycle mechanical life, the GEF0125FT4 is engineered for dependable industrial service. Its lug or bar terminals, M8 connections and flexible mounting orientation support integration into professional switchboards, machinery and power-distribution panels.
