Square D Services Medium Voltage Substation Circuit Breakers

For over 100 years, Square D products rom Schneider Electric have been

setting standards in quality or the electric industry and serving utilities with

highly reliable products. By combining the latest developments in circuit

breaker technology with world-renowned quality, the Powersub Type EVR

Vacuum Substation Circuit Breakers rom Square D Services are the mostadvanced medium voltage circuit breakers available.

Compliance to ANSI StandardsDesigned and tested to comply with or exceed ANSI and

IEEE standards or outdoor circuit breakers.

ISO 9001 CertifcationDesigned and manuactured in a acility that is Quality Systems

Certifed by Underwriters Laboratories, Inc. to ISO 9001.

Benefts

High-speed operation

Interrupting time o 3 cycles or less

Long lieHermetically sealed interrupters protect contacts rom

corroding elements and contamination.

Ease o maintenanceInterrupter assemblies and contact wear indicators accessible via a

bolted panel.

ReliabilityA minimum o moving parts on the motor-driven, spring-charged

Type RI mechanism.

Durability

Robust design tested to the highest IBC-2000 seismic standard.Other seismic standards may be evaluated upon request.
