3VJ MCCB, Thermal Magnetic Trip Unit - 3VJ1220-6EB42-0AA0

Product Description

3VJ MCCB, Thermal Magnetic Trip Unit – 3VJ1220-6EB42-0AA0

The Siemens 3VJ1220-6EB42-0AA0 is a robust Molded Case Circuit Breaker (MCCB) from the 3VJ1 series, designed for reliable protection of low-voltage electrical distribution systems. It uses a thermal magnetic trip unit (ATFM) that provides dependable protection against overload and short-circuit faults, ensuring safe operation of cables, switchboards, and connected electrical loads.

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

Based on Siemens 3VJ1 technical design standards, the 3VJ12 frame family typically supports around 200 A rated current and up to 36 kA breaking capacity at 415 V AC (variant dependent), making it suitable for demanding LT applications in industrial environments.
