Siemens 3VJ MCCB – Thermal Magnetic Trip Unit –
3VJ1112-4EB42-0AA0
The Siemens 3VJ1112-4EB42-0AA0 is a SENTRON 3VJ
series molded case circuit breaker (MCCB) designed for dependable
protection of low-voltage electrical distribution systems against
overload and short-circuit faults. It is widely used in industrial
switchboards, PCC/MCC panels, OEM machinery, commercial electrical systems, and
infrastructure applications where reliable protection and safe power
distribution are essential.
This MCCB belongs to the 3VJ11 frame size and is
equipped with a thermal magnetic trip unit (ATFM – Adjustable Thermal Fixed
Magnetic). It provides adjustable overload protection together with fixed
magnetic short-circuit protection for improved protection coordination and
reliable circuit safety.
With a rated current of 125A, 4-pole configuration,
and high interruption capability, this breaker is suitable for demanding
industrial and commercial power distribution applications.
