Medium-Voltage Vacuum Replacement Circuit Breakers

General Information

Description
Wyle Laboratories
Available Replacement Breaker Models

Direct vacuum replacement breakers provide a cost effective way to upgrade your system capabilities while saving you from costly maintenance and lost productivity.
Whether your original air-magnetic switchgear was made by Allis-Chalmers, Westinghouse, GE, Federal Pacific, ITE, McGraw Edison, or another manufacturer, we will assist you to evaluate the Siemens vacuum replacement, retrofit, or retrofill option that best meets your needs.

Why Replacement Breakers?

Increased reliability and performance
Reduced operating and maintenance expenditures
Reduced downtime, minimal changeover time during power switchgear modification or conversion
Preserved investment in existing cubicles
Improved employee and environmental safety.

Why Siemens?

Superior performance, longer service life
Standard 3AH operator on all siemens replacement, medium voltage distribution and outdoor vacuum circuit breakers
MOC-Saver™ provides reliable operation of existing MOC system (applicable models)
Extensive replacement breaker and retrofit experience - 800+ projects since 1983.
Nuclear 1E rated
Testing per ANSI, IEEE C37.59 - 2007
Full range of service capabilities by skilled factory-trained engineers and technicians.

Wyle Laboratories is teamed with Siemens to provide a complete line of 1E low & medium-voltage circuit breakers to the US nuclear industry.

Siemens has replacement breaker designs for most Allis-Chalmers design including the MA, MB, MC, MCV (Siemens MSV), FA, FB, FC, FCV (FSV), and AM (AMR). Siemens has many design for the GE Magneblast, Westinghouse DH/DHP, ITE HV/HK, Federal Pacific DST2, and McGraw Edison PSD.
