SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1112-4ED32-0AA0

Product Description

Siemens SENTRON 3VM1112-3ED42-0AA0 – Thermal Magnetic Trip Unit MCCB

The Siemens 3VM1112-3ED42-0AA0 is a robust SENTRON 3VM molded case circuit breaker (MCCB) designed for reliable protection of electrical distribution systems against overload and short-circuit faults. It belongs to the 3VM1 IEC Frame 160 series and is widely used in industrial switchboards, MCC panels, and power distribution networks.

This model is equipped with a TM220 thermal magnetic trip unit, providing adjustable overload protection (thermal) and fixed instantaneous short-circuit protection (magnetic). It ensures safe disconnection of fault currents while maintaining stable operation under normal load conditions.

With a breaking capacity of 25 kA at 415 V AC, it is suitable for medium-duty industrial applications, motor feeders, and distribution systems where reliable protection and high safety standards are required.
