Power Break® II Switches

Chapter 1. Introduction

1-1 Overview

Power Break® II insulated-case switches are designed to serve low-voltage power circuits and equipment. They are available with and Power+™ Control Units for operation of accessories and optional ground-fault detection.

1-2 Receiving the Switch

Unpack the switch and inspect it for shipping damage. Ensure that the switch has the proper current, voltage, and interruption ratings for the application by comparing the catalog number with the table in the Getting Started section on the inside front page.

The weights of the various frame sizes are listed in Table 1, for reference.

Storage

The switch should be placed in service immediately in its permanent location. However, if it must be stored for an indefinite period, it should be carefully protected against condensation, preferably by storage in a warm dry room. Switches for outdoor equipment should be stored in that equipment only when power is available and heaters are in operation, to prevent condensation.

The switch should be stored in a clean location, free from corrosive gases or fumes. In particular, protect the switch from moisture and cement dust, as that combination may be corrosive.

If the switch is stored for any length of time, it should be inspected periodically to ensure good mechanical condition.

1-3 Preparation for Installation

Bolted Electrical Connections

Using an industry-accepted solvent, remove any foreign material from the line and load strap surfaces and the corresponding surfaces of the connecting bus. Ensure that the mating surfaces are smooth and free of burrs and nicks.

Place the bus connections in position and align the mounting holes. Insert and fasten the mounting bolts and washers according to specifications in Table 2.

Panel Cutouts and Clearances

Use the following information to prepare the equipment and assure proper clearances for installation and operation of the switch.

Figures 1 and 2 show the front-panel escutcheon cutout patterns and the locations of the switch mounting bolts. The standard door cutout dimensions require a trim plate on the switch. The optional dimensions are for flush front or nonhinged door construction and the trim plate may be omitted. Ventilation cutouts are required for stationarymounted switches rated 1600 A and larger and for drawout switches rated 2000 A and larger. Ventilation cutouts

not

are frame switches or for stationary-mounted 800 A frame switches.

Because of arc chamber venting, the minimum throughair distance from the top of the switch’s molded case to grounded metal for 800–2000 A switches is 4.50 inches [114 mm] in an area 5.31 inches x 16.00 inches [135 mm x 406 mm], centered over the vent screens. (Refer to outline drawings 10054370, Sheets 1–5, for details.)

For 2500–4000 A switches, the minimum through-air distance from the top of the switch’s molded case to grounded metal is 8.00 inches [203 mm] in an area 9.00 inches x 16.00 inches [227 mm x 406 mm], over the vent screens. (Refer to outline drawings 10055629, Sheets 1–7, for details.)
