Siemens 3VJ MCCB – Thermal Magnetic Trip Unit –
3VJ1216-5EA42-0AA0
The Siemens 3VJ1216-5EA42-0AA0 is a SENTRON /
SINOVA 3VJ series molded case circuit breaker (MCCB) designed for reliable
protection of low-voltage distribution systems against overload and
short-circuit faults. It is widely used in industrial panels, PCC/MCC
switchboards, OEM machinery, HVAC systems, and commercial electrical
installations where compact design and dependable fault interruption
are required.
This model belongs to the 3VJ12 frame series and is
equipped with a thermal magnetic trip unit (FTFM – Fixed Thermal Fixed
Magnetic), providing fixed overload and fixed short-circuit protection
for simple and maintenance-free operation in standard distribution
applications.
It is a 3-pole MCCB with 160A rated current and 36kA
breaking capacity at 415V AC, making it suitable for medium-duty feeder
and distribution systems requiring higher fault level protection and stable
coordination.
