Siemens 3VJ10 MCCB – Thermal Magnetic Trip Unit – 3VJ1005-1DB32-0AA0
The Siemens 3VJ1005-1DB32-0AA0 is a SENTRON 3VJ10 series molded case circuit breaker (MCCB) designed for protection of low-voltage electrical distribution systems against overload and short-circuit faults. It is widely used in industrial switchboards, MCC panels, and feeder distribution systems where reliable and compact protection is required.
This model belongs to the 3VJ10 frame class (125A platform) and is equipped with a thermal magnetic trip unit (ATFM – Adjustable Thermal, Fixed Magnetic). It provides adjustable overload protection and fixed instantaneous short-circuit protection, enabling improved coordination with downstream protection devices.
With a rated current of 50A and a breaking capacity of 18kA at 415V AC, it is suitable for industrial and commercial feeder applications where medium fault-level protection is required.
