Siemens 3VJ MCCB – Thermal Magnetic Trip Unit –
3VJ1216-5DB32-0AA0
The Siemens 3VJ1216-5DB32-0AA0 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 switchboards,
PCC/MCC panels, OEM machinery, commercial buildings, and infrastructure
projects where compact size and high fault interruption capability
are required.
This model belongs to the 3VJ12 frame series and
features a thermal magnetic trip unit (ATFM – Adjustable Thermal Fixed
Magnetic). It provides adjustable overload protection with fixed
instantaneous short-circuit protection, ensuring stable coordination in
feeder and distribution circuits.
It is a 3-pole MCCB with 160A rated current and 36kA
breaking capacity at 415V AC, making it suitable for medium-duty
industrial distribution and feeder protection applications.
