Distribution Circuit Breaker Features Magnetic-Actuator Operator

Siemens Infrastructure & Cities’ Low and Medium Voltage division has released 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.

“Some of our customers have been telling us that they prefer a magnetic-actuator operator in their distribution breakers,” says Jaime Dulac, vice president and general manager of the Medium Voltage business unit.

The type SDV7-MA circuit breaker uses a monostable magnetic-actuator design that provides advances over the bistable design, with faster opening times and significantly less force required to manually trip the circuit breaker.
