3VJ10 MCCB, Thermal Magnetic Trip Unit - 3VJ1003-1EA42-0AA0

Product Description

Siemens 3VJ10 MCCB – Thermal Magnetic Trip Unit – 3VJ1003-1EA42-0AA0

The Siemens 3VJ1003-1EA42-0AA0 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 commonly used in industrial switchboards, MCC panels, and OEM power distribution systems where compact design and reliable protection are required.

This model belongs to the 3VJ10 frame class (up to 125 A range) and is equipped with a thermal magnetic trip unit (FTFM – Fixed Thermal Fixed Magnetic), providing fixed overload and fixed instantaneous short-circuit protection for consistent and maintenance-free operation.

With a rated current of 32 A and a breaking capacity of 18 kA at 415 V AC, it is suitable for standard industrial and commercial applications with moderate fault level requirements.
