SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1116-4EE32-0AA0

Product Description

Siemens SENTRON 3VM MCCB – Thermal Magnetic Trip Unit – 3VM1116-4EE32-0AA0

The Siemens 3VM1116-4EE32-0AA0 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 commonly used in industrial switchboards, MCC panels, and feeder distribution systems where reliable, compact, and high-performance protection is required.

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

With a rated current of 160 A and a breaking capacity of 36 kA at 415 V AC, it is suitable for demanding industrial applications requiring higher short-circuit withstand capability compared to standard 25 kA variants.
