Why Choose the Lovato GEF0100N 3-Pole 100 A Switch Disconnector with NH Fuse Holder?
The Lovato GEF0100N is a three-pole 100 A switch disconnector with integrated NH fuse holders, combining manual circuit isolation with fuse-based overcurrent protection in a compact industrial switching device. Part of the Lovato GEF switch disconnector range, it is designed for AC power distribution, machinery and switchboard applications.
The GEF0100N has an IEC conventional free-air thermal current of 100 A, with an AC-21A operational current of 100 A at 400 V and an AC-23A operational current of 80 A at 400 V. Its integrated NH fuse-holder arrangement allows compatible NH fuse links to be incorporated directly into the switching assembly.
Designed for screw mounting onto a plate, the GEF0100N can be installed in different orientations to suit panel layouts. Transparent front windows facilitate visual monitoring of the fuse area, while Lovato offers direct and door-coupled operating arrangements using separately selected handles and shaft extensions.
Key Advantages
- Combines switch disconnection and NH fuse holding in one coordinated device.
- Three-pole configuration for three-phase AC circuits.
- 100 A conventional thermal current for industrial power distribution.
- 100 kA conditional short-circuit current for robust protected installations.
- Compact modular construction helps optimise space inside electrical panels.
- Supports direct or door-coupled operation using compatible Lovato accessories.
Key Features

Combined Circuit Isolation and Fuse Protection
Fused switch disconnectors combine a manually operated isolation function with fuse holders, allowing compatible fuse links to provide circuit protection while the switching mechanism provides controlled disconnection. This integrated approach is particularly useful in industrial switchboards and machinery where compact power switching and fuse protection are required together.
The Lovato GEF0100N uses NH fuse holders and transparent front windows to support convenient fuse inspection. Its compact design, flexible mounting orientation and compatibility with direct or door-coupled operating accessories allow panel builders to adapt the device to different enclosure and switchboard configurations.
Typical Applications
- Industrial power distribution switchboards.
- Machine and equipment incoming supply isolation.
- Motor control centres.
- Industrial automation and control panels.
- Three-phase fused distribution circuits.
- Electrical installations requiring combined manual isolation and NH fuse protection.
