Siemens Infrastructure & Cities' Low and Medium Voltage division announces the release of the new type SDV7-MA distribution circuit breaker that provides a magnetic-actuator operator as an alternative to the established stored-energy operator in the type SDV7 outdoor vacuum circuit breaker family.
The type SDV7-MA circuit breaker uses a monostable magnetic-actuator design, which provides advances over the bistable design, with faster opening times and significantly less force required to manually trip the circuit breaker.
The design of the type SDV7 features significant reduction in enclosure size and, consequently, in the overall footprint. The type SDV7 product line encompasses the voltage groups: 15.5 kV and 27.6 kV. Each group is specifically designed to optimize space and material for the voltage class while retaining common features across the entire product line.
