250A, 400A & 630A, 415V AC, SIZE 1, 2, 3.
Suitable for Single/Triple Pole Switching
The Fuse Switches are suitable to be used in Distribution Boards, Power Control Centers, Cable Pillar Boxes etc. The fuse switches guarantee operational safety against accidental contact and have adequate breaking capacity.
Due to their compact design & easy mounting, it is economical to use vertical type fuse switches in the LV Distribution boards. The overall dimension of the LV Distribution boards are reduced with their use and therefore the total cost of the switchgear is thus essentially cutdown.
» The fuse switch can be closed on the short circuit fault without danger to the operator.
» High making and breaking capacity, utilization category AC 22 as per IEC 60947 and also high degree of short circuit making capacity.
» Body is made from high quality glass fiber reinforced polyster (DMC) which is mechanically strong, heat resistant & self-extinguishing type. The contacts are of copper Tin/silver plated, spring assisted provided with arc chutes with adequate number of splitter plates for quenching the arc. The arc chutes are provided on top and bottom which increases the life of the fixed contacts.
» The downward connections are of electrolytic copper tin plated which are brought to one level at the bottom for cable termination with phase L1 on the left hand side. The hinged front cover is 3x Single Pole/Triple-Pole Switchable.
» Protection against accidental contact with live parts even if the switch cover is open.
» HRC Fuse Switches generally meet the requirement of IEC 60947.
