Application
The primary purpose of any fuse cutouts is to provide protection to the lines of your system and the various apparatus on those lines such as transformers and capacitor banks. Fuse cutouts provide reliable protection from low-level overloads that just melt the fuse link, intermediate faults, and very high faults, through maximum interrupting capacity.
Quality Construction
Top Contact
The top contact is attached to the galvanized-steel hood by a stainless rivet to provide a smooth self - aligning action during closing even in severely corrosive environments. The top contact provides a socket-type cavity for latching the fuse holder and prevents any possible "over-travel of the fuse holder. The top contact is made of a highly conductive copper strip with silver-plated embossments to resist corrosion. The contacts are held under constant pressure designed to maintain firm contact with the fuse holder contact surface until fault interruption is accomplished."
Hinge
The hinge on the Fuse cutout employs large pivot areas for the fuse holder 's trunnion and is cast of a copper alloy chosen for its strength and corrosion resistance.The hinge contacts are highly conductive copper alloy stampings and are plated to assure low resistance current transfer from the trunnion casting. The parallel current paths are backed up by high strength cantilever springs and are riveted to the hinge castings.Fuse holder can be dropped into place and easily lifted up and out. No tricky maneuvering.
Fuse holder
The solid cap on the single ventfuse holder is a copper alloy,silver-plated to provide efficient current transfer.An integral ring is provided in the top tube casting for opening and closing the fuse holder with conventional disconnect tools from the ground, from a bucket truck or from the pole.
The toggle type trunnion casting is a selective silver-plated bronze for efficient current transfer to the lower hinge contacts. A cam shaped projection on each side of the trunnion casting provides high pressure parallel current paths to the lower contacts. These projections, or pivot pins,are cast full round for smooth rotational operation in the hinge. The link ejector assists in arc interruption during low fault current or exces-sive overload conditions.A groove in the center minimizes bending stresses in the pigtail to prevent broken strands. A stainless steel torsion spring on the link ejector helps to rapidly eject the link from the bore of the fuse holder during interruption. The 200 ampere link ejector has a wider groove area and increased spring force to accommodate the larger links.
Fuse tube
The 1/2-inch inside diameter of the Fuse cutouts 100 ampere fuse tube increases internal pressure giving superior an reliable expulsion action.During frequently encountered intrmediate fault ranges this diameter also permits higher TRV(transient recovery voltage) values to be tolerated. This small bore design eliminates any concern related to high impedance phase-to-phase faults on ungrounded wye and delta systems. The inside liner is constructed of a synthetic-quenching material.The tube is made of fiberglass which permits the smaller bore and provides a higher burst strength. It is protected from the weather and environment by a special ultra- violet resistant coating.
Also, the XIYA fuse tube operates with fuse links from all major suppliers.
Mounting Bracket
Fuse cutouts come packed one per carton including a NEMA Haeavy Duty "B" bracket with captive 11/2" bolt for cross arm mounting.
Type "X" bracket, also for cross arm mounting, provides 25/8" additional clearance between the cross arm and the cutout.
Higher Interrupting Capacities
By using a copper arc shortening rod inside the top of the fuse tube, higher interrupt ratings are obtainable. An arc shortening rod is attached to the cap of some fuse tube and lowers the fuse link within the fuse tube. This permit a much shorter arc, resulting in less arc energy, and higher interrupting capacities.
For 200 A tubes, it allows for full voltage rating. It is necessary to use fuse links with removable button heads when arc shortening rods are employed.
