Product Description

3VJ MCCB, Thermal Magnetic Trip Unit – 3VJ1225-3DA32-0AA0

The Siemens 3VJ1225-3DA32-0AA0 is a high-performance Molded Case Circuit Breaker (MCCB) from the 3VJ1 series, designed to provide reliable protection for low-voltage electrical distribution systems. It uses a thermal magnetic trip unit (FTFM) to ensure dependable protection against overload and short-circuit faults, safeguarding cables, equipment, and downstream loads.

This MCCB is widely used in industrial switchboards, commercial distribution panels, OEM machinery, and infrastructure power systems, where high fault interruption capacity, compact design, and stable performance are essential for continuous operation.

According to Siemens technical data, the 3VJ12 frame series (250 A class) offers strong short-circuit performance with a breaking capacity up to 25 kA at 415 V AC, making it suitable for medium-duty industrial applications.
