Siemens 3VJ10 MCCB with Thermal
Magnetic Trip Unit – 3VJ1012-1EA42-0AA0
The Siemens 3VJ1012-1EA42-0AA0
is a Molded Case Circuit Breaker (MCCB) from the SENTRON 3VJ10 series,
designed to deliver reliable protection for low-voltage systems against overload
and short-circuit faults. This 4-pole MCCB is equipped with a Thermal
Magnetic Trip Unit (ATFM type), offering adjustable overload protection
and fixed short-circuit protection, making it suitable for industrial and
commercial power distribution systems.
It is widely used in LT panels, MCC/PCC panels, feeder circuits, and industrial distribution boards, where neutral switching and full 4-pole protection are required.
