Siemens has added new versions and product features to its 3VA series of molded case circuit breakers (MCCB) from its Sentron portfolio. The 3VA1 series is now available for a higher rated current of up to 250 A and has been expanded to include starter protection variants. Siemens also now offers the 3VA2 series in motor protection and starter protection variants that protect the electric drives against short-circuits and overloads. The company also improved the selectivity characteristics of the devices. The 3VA series thus meets all energy distribution requires for protecting cables, electrical loads and industrial equipment against electrically induced damage and down times.
