SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1112-4GE42-0AA0

Product Description

Siemens SENTRON 3VM1112-4GE42-0AA0 – Thermal Magnetic Trip Unit MCCB

The Siemens 3VM1112-4GE42-0AA0 is a SENTRON 3VM molded case circuit breaker (MCCB) designed for reliable protection of low-voltage electrical distribution systems against overload and short-circuit faults. It is widely used in industrial switchboards, MCC panels, and power distribution systems where stable and safe circuit protection is required.

This breaker belongs to the 3VM1 IEC Frame 160 series and is equipped with a TM220 thermal magnetic trip unit, which provides adjustable thermal overload protection and fixed instantaneous short-circuit protection. It ensures safe interruption of fault currents while maintaining continuity of power under normal operating conditions.

With a breaking capacity of 25 kA at 415 V AC, this MCCB is suitable for medium-duty industrial applications, motor feeders, and distribution networks requiring dependable protection and compact design.
