3VJ10 MCCB, Thermal Magnetic Trip Unit - 3VJ1003-0DB32-0AA0

Product Description

Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit – 3VA1040-3ED42-0AA0

The Siemens 3VA1040-3ED42-0AA0 is a SENTRON 3VA1 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, MCC panels, and feeder distribution systems where compact design and high fault-breaking performance are required.

This model belongs to the 3VA1 IEC Frame 100 series and is equipped with a thermal magnetic trip unit (TM210 / FTFM – Fixed Thermal Fixed Magnetic). It provides fixed overload protection and fixed instantaneous short-circuit protection, ensuring consistent performance without the need for field adjustment.

With a rated current of 40 A and a high breaking capacity of 36 kA at 415 V AC, it is suitable for demanding industrial applications where strong short-circuit protection and system reliability are critical.
