Loadbuster ®—The S&C Loadbreak Tool

A Better Way of Switching
S&C’s Loadbuster is the original light-weight, easy-to-use loadbreak tool for use with disconnects, cutouts, and power fuses. It brings load switching capability through 34.5 kV and 600 amperes nominal, 900 amperes maximum to a wide variety of devices on your distribution system.

Greater Flexibility at Lower Cost
Having an arc-interrupting device built into every disconnect, cutout, and power fuse on your distribution system is needlessly expensive. Loadbuster, S&C’s portable loadbreak tool, brings the interrupter to the disconnect, cutout, or power fuse whenever load-switching capability is needed . . . but only when needed. Costs are limited to one Loadbuster tool for each line truck. An acceptable minimal cost is spread across your entire system.

Power Consumers Benefit
Loadbuster switching helps keep service interruptions to a minimum. There’s no need for complex switching procedures involving opening and reclosing of line and feeder breakers to permit dead switching. There’s no need for one or more line crews to travel and retravel miles of system. Every disconnect, cutout, and power fuse becomes a sectionalizing point. Live switching can be done at the point that minimizes the length of the planned outage and affects the fewest consumers.

Foolproof Operation
Operation is simple, positive. Loadbuster’s
anchor is simply hung on the attachment hook of the disconnect, cutout, or power fuse; then the pull ring is engaged with Loadbuster’s pull-ring hook, held fast by the pull-ring latch. A firm, steady downward pull opens the switching device and trips

Loadbuster, interrupting the circuit—there’s no external arc, no contact burning. Loadbuster can be instantly reset for the next operation.

There are no “booby trap” arc chutes and auxiliary blades on Loadbuster-operable switching devices to concern operating personnel, nor “gingerbread” mechanisms to challenge them.

Loadbuster can handle 1500 to 2000 operations between inspections. Just a minimum of attention keeps it in top- notch condition. And with Loadbuster’s operation counter, monitoring usage is easy.

Universality
Not only can Loadbuster switch load currents up through 600 amperes nominal, 900 amperes maximum at distribution system voltages up through 34.5 kV . . . it can break the associated transformer-magnetizing, line- charging, and cable-charging currents. And it can switch single capacitor banks typically found on distribution systems within its voltage rating.
