3VJ10 MCCB, Thermal Magnetic Trip Unit - 3VJ1003-1DA32-0AA0

Product Description

Siemens 3VJ10 MCCB – Thermal Magnetic Trip Unit – 3VJ1003-1DA32-0AA0

The Siemens 3VJ1003-1DA32-0AA0 is a SENTRON 3VJ10 series molded case circuit breaker (MCCB) designed for protection of low-voltage power distribution systems against overload and short-circuit faults. It is widely used in industrial switchboards, MCC panels, and OEM electrical systems where compact size and reliable fault protection are required.

This model belongs to the 3VJ10 frame class (up to 125 A category) and features a thermal magnetic trip unit (FTFM – Fixed Thermal Fixed Magnetic), meaning both overload and short-circuit protections are factory set 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 distribution applications where moderate fault levels are expected.
