3VJ10 MCCB, Thermal Magnetic Trip Unit - 3VJ1004-3EB42-0AA0

Product Description

Siemens 3VJ10 MCCB – Thermal Magnetic Trip Unit – 3VJ1004-3EB42-0AA0

The Siemens 3VJ1004-3EB42-0AA0 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 (125 A 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, ensuring proper coordination with downstream devices.

With a rated current of 40 A and a breaking capacity of 25 kA at 415 V AC, it is suitable for industrial and commercial feeder applications where moderate fault levels are expected.
