Etien Vertical Fused Load Disconnectors ensure the safe opening and closing of circuits under power in electrical distribution panels. It is a user-friendly product thanks to the secure mounting of NH blade fuses in the system. Protection against overcurrents is maximized with NH blade fuses. By adding an integrated current transformer, it offers a compact solution for measurement needs and energy monitoring systems.

Etien Vertical Fused Load Disconnectors have been proven to comply with the TS EN 60947-3 / IEC 60947-3 standard through type tests conducted in internationally accredited laboratories.

Vertical Fused Load Disconnector Material Specifications

Designed for use with NH000, NH00, NH0, NH1, NH2, and NH3 fuses.
The three phases can be switched on together or separately.
It has a high cutting capacity.
The lower body material is made of BMC material, which has very high mechanical strength and electrical insulation properties and is heat and flame resistant with a V0 fire resistance class.
The contacts of the NH blade fuse holder are silver-plated.
The indicator showing that the NH blade fuse has tripped is visible from the outside.
Power losses are low.
Current transformers placed at the rear allow for the measurement of currents in each phase.
Suitable for 400V AC23B and 500V AC22B usage classes.
All fasteners (bolts, washers, nuts) are made of corrosion-resistant stainless steel.
Thanks to its locking feature in the parking position, the maintenance and repair safety of the line supplied by the Load Disconnector is ensured.
