SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1125-4EE32-0AA0

Product Description

Siemens SENTRON 3VM MCCB – Thermal Magnetic Trip Unit – 3VM1125-4EE32-0AA0

The Siemens 3VM1125-4EE32-0AA0 is a SENTRON 3VM1 series molded case circuit breaker (MCCB) designed for 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 reliable protection and compact design are required.

This model belongs to the 3VM1 Frame 160 series and is equipped with a thermal magnetic trip unit (TM220 / ATFM – Adjustable Thermal, Fixed Magnetic). It provides adjustable overload protection and fixed instantaneous short-circuit protection, ensuring stable coordination and reliable fault interruption.

With a rated current of 25 A and a breaking capacity of 36 kA at 415 V AC, it is suitable for industrial and commercial applications requiring higher fault-level protection in compact feeder circuits.
