MSV & FSV Medium Voltage Replacement Circuit Breakers ANSI 4.76/8.25/15kV at 250–1000 MVA, 1200-3000 Amperes Replacement breakers provide a costeffective way to upgrade your system capabilities while saving you from costly maintenance and lost productivity while preserving your investment in existing cubicles and cables. Why Siemens? Siemens Offers the Best Vacuum Circuit Breaker in the Industry. Siemens provides the experience your company needs to successfully extend the life of your equipment. Our circuit breakers are manufactured using the same fixtures as the original AllisChalmers, Siemens-Allis breakers. 5-MSV (Replacement for Allis-Chalmers MA) Increased Reliability and Performance Reduced Operating and Maintenance Expenditures Reduced Downtime, Minimal Changeover Time During Upgrade Preserved Investment in Existing Cubicles Improved Employee and Environmental Safety 10,000 full load operation, 10-year maintenance cycle on replacement circuit breakers with 3AH operator Standard Operator on All Siemens Replacement, Medium Voltage Distribution, and Outdoor Vacuum Circuit Breakers Extensive Replacement Breaker Experience – 750+ projects since 1983 Over 300,0000 3AF/H series circuit breakers in service worldwide Why Replacement Breakers? Superior Performance, Longer Service Life Nuclear 1E Rated (350+ breakers) Closed Door Racking Modification In order to improve operator safety, Siemens offers a field modification to convert type D and F switchgear to a closed-door, remote rack design. This modification provides a cost effective solution to keep operators clear of the arc flash zone during breaker racking.

These additions allow end-users to either have closed-door manual racking, or closed door remote racking. 5 MSV 5 FSV 7/15 FSV A 67.00 80.06 80.06 B 22.63 31.13 31.13 C 12.00 12.00 12.00 D 26.00 31.00 31.00 E 31.00 44.50 44.50 Sample Dimensional Diagram - MSV The closed door remote racking option requires the above mentioned cell and breaker additions, as well as a minor front panel modification to accept a torque-regulated motor. The motor can be moved from one cell position to the next, thus only one motor device is required.
