SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1116-3GE42-0AA0

Product Description

Siemens SENTRON 3VM1116-3GE42-0AA0 – Thermal Magnetic Trip Unit MCCB

The Siemens 3VM1116-3GE42-0AA0 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 feeder distribution systems where stable and safe power interruption is required.

This device belongs to the 3VM1 IEC Frame 160 series and is equipped with a TM220 thermal magnetic trip unit (ATFM – Adjustable Thermal, Fixed Magnetic). It provides adjustable overload protection (Ir adjustable) and fixed instantaneous short-circuit protection, ensuring both flexibility and dependable fault clearing.

With a rated current of 160 A and a breaking capacity of 25 kA at 415 V AC, it is suitable for industrial feeder circuits, motor control centers, and general power distribution applications requiring reliable short-circuit protection.
