Siemens 3VJ MCCB – Thermal Magnetic Trip Unit –
3VJ1112-5EA42-0AA0
The Siemens 3VJ1112-5EA42-0AA0 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 widely used in industrial switchboards, PCC/MCC
panels, OEM machinery, commercial electrical systems, and infrastructure
applications where dependable circuit protection and operational safety are
essential.
This MCCB belongs to the 3VJ11 frame size and is
equipped with a thermal magnetic trip unit (FTFM – Fixed Thermal Fixed
Magnetic). It provides fixed overload and fixed magnetic short-circuit
protection for simple and reliable operation in industrial power distribution
systems. The breaker features a 4-pole configuration, making it suitable
for applications requiring phase and neutral protection.
With a rated current of 125A and a breaking
capacity of 36kA at 415V AC, this MCCB is ideal for demanding commercial
and industrial electrical installations.
