The Reliability of a Quality Design

The quality of Square D MASTERCLADTM medium voltage

metal-clad switch gear stems from a design and manufac-

turing process that focuses on long-term switch gear

performance with the highest degree of reliability.

Reliable performance and safety is enhanced by the

rugged construction of MASTERCLAD switch gear. Each

switch gear assembly consists of individually grounded,

compartmentalized steel structures (with -gauge barriers

between vertical sections and major parts of each primary

circuit) to protect operating personnel.

Based on specific customer application needs, Square D

engineers and technicians select the appropriate standard

sections and bus configurations, with the ability to

customize where needed. After the specified circuit breakers,MASTERCLADswitch gearcomponents includeavailable state-of-the-art electronicslike POWERLOGIC

power monitoringand control systems,

digital microproces-sor-based protectiverelays and SY-MAXPLC-based automaticthrowover systems.

instrument and control power transformers, relays, meters

and other components are selected and approved, all are

factory-assembled, wired and tested as a complete

assembly. This testing is performed to insure reliability

by energizing the control circuits and verifying the specified

sequence of operation for each metal-clad switch gear

project along with the ANSI C37.20.2 Production Tests.

ApplicationsMASTERCLAD mediumvoltage switch gear is usedin a wide variety of switch-ing, control and protective

applications includingelectric utility generationand distribution systems,industrial plants, commer-cial buildings, hospitals,municipal pumping stations,wastewater treatment

plants, transportationsystems, and pipelinestations. Transformers,

motors, generators,capacitors, distributionlines, and feeder circuitsare protected by thisclass of switch gear .Significantly, most of theMASTERCLAD switch gearspecified for theseapplications is relied uponto provide the criticalmain service entranceprotection and controls.

Standardization

Standardization of thedesign incorporates aseries of basic modularunits, control packages,and instrumentation. Formost switch gear ratings,circuit configurations andfunctions, one basic sizeunit is used. These features

provide applicationflexibility, versatility,efficiency and economy in

minimizing engineeringtime to plan and layoutthe switch gear .

Convenient Handling

The VR breaker is ahorizontal drawout typedesigned to provide longlife, reduced maintenanceand ease of handling. Thebreaker truck has wheelsfor easy movement into a

ComprehensiveTest Program

A comprehensive designtesting program has beenperformed by Square Ddevelopment engineers. Theswitch gear and breakersare designed and testedin accordance withallapplicable ANSI StandardsC37.04, C37.06, C37.09 andC37.20.2. The switch gearand breakers meet therequirements of ANSI,IEEE, NEMA, and generallyexceed IEC standards.

Features and Benefits

Long Life/MinimumMaintenance

Reliability is the mainpriority. The VR vacuumcircuit breakers aredesigned for long life.The interrupter's copper-chromium contacts,hermetically sealed for lifein a vacuum, are protectedfrom external atmosphericinfluences. Dust, moisture,and all other possiblecontaminants are sealedout. This state-Qf-the-artvacuum interrupter designis capable of 20-100 fullfault interruptions (varies

by rating).

The high dielectric strengthof the vacuum environmentallows a very short clearingtime during fault interrup-tion to limit the energydissipated into the arc.Total fault clearing time isless than 3 cycles andcontact travel is only 3/8 to1/2 inch, depending on theratings of the circuit breaker .The short stroke producesless mechanical shock tothe operating mechanism.

For evaluation of wear onthe main contacts over thelife of the circuit breaker ,contact erosion indicationis provided on each

interrupter pole assembly.

Together with a totalcommitment to quality,these features provide longlife with high reliability.
