Loadbuster^® Tool

Introduction

Loadbuster is the original lightweight, easy-to-use portable loadbreak tool for use with disconnects, cutouts, power fuses, and fuse limiters. It brings load-switching capability through 34.5 kV and 600 amperes nominal, 900 amperes maximum to your overhead distribution system.

Loadbuster cuts installation and operation costs. There’s no need for load interrupters on each device. Switching procedures are simplified too . . . minimizing the duration and scope of outages. This rugged, reliable device interrupts with no external arc, meeting OSHA requirements for opening circuits under load.

Loadbuster is available in two system-matched models:

• 14.4/25 kV nominal, 27 kV maximum
• 25/34.5 kV nominal, 38 kV maximum

Both interrupt up to 600 amperes nominal, 900 amperes maximum.

Certain application restrictions apply, especially with regard to single-pole switching of ungrounded-primary three-phase transformers or banks of single-phase transformers. See S&C Publication 811-30 for details.

A new operation counter feature — available at no additional charge — lets Loadbuster users monitor the use of their tools . . . thus helping them make more informed decisions with regard to inspection and maintenance. The non-resettable operation counter is built into Loadbuster’s silencer, and can easily be added to existing tools during routine maintenance checks.

In addition to the operation counter, Loadbuster Tools also feature redesigned internal components for enhanced operating life — now 1500 to 2000 “mixed-duty” operations between inspection and maintenance. (Previously, inspection and maintenance were recommended after 500 to 1000 operations.) The term mixed duty refers to a mixture of line charging currents, distribution-transformer-magnetizing currents, pole-top capacitor bank currents, and moderate parallel or loop load currents, with occasional switching of heavier load currents.

S&C’s Loadbuster Tools are manufactured in accordance with a quality system certified to ISO9001:2000.
