Siemens 3VJ MCCB – Thermal Magnetic Trip Unit –
3VJ1112-6EB42-0AA0
The Siemens 3VJ1112-6EB42-0AA0 is a SENTRON 3VJ
series molded case circuit breaker (MCCB) designed for reliable protection
of low-voltage electrical distribution systems against overload and
short-circuit faults. It is commonly used in industrial switchboards,
PCC/MCC panels, OEM machinery, commercial buildings, and infrastructure
projects where stable performance and compact protection devices are
required.
This MCCB belongs to the 3VJ11 frame series and is
equipped with a thermal magnetic trip unit (ATFM – Adjustable Thermal Fixed
Magnetic). It provides adjustable overload protection along with fixed
magnetic short-circuit protection, ensuring dependable coordination and
fault isolation in electrical networks.
With a rated current of 125A and a breaking
capacity of 36kA at 415V AC, this breaker is suitable for medium-duty
industrial and commercial power distribution applications requiring
reliable short-circuit interruption and long operational life.
