Siemens as a leading power and automation technology group, introduced its new 3VM moulded case circuit breaker (MCCB) for building, infrastructure and industrial applications. Siemens has added new versions and product features to its 3VM series of moulded case circuit breakers (MCCB) from its Sentron portfolio. Moulded case circuit breakers (MCCB) are one of the most important components in the modern low-voltage power distribution. In buildings and industrial plants, moulded case circuit breakers protect cables and electrical loads from damage and failures that can be caused by disruptions such as short circuits or overload.
