SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1132-5GE42-0AA0

Product Description

Siemens SENTRON 3VM MCCB – Thermal Magnetic Trip Unit – 3VM1132-5GE42-0AA0

The Siemens 3VM1132-5GE42-0AA0 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 high fault-level 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 (Ir: approx. 22–32 A) and fixed instantaneous short-circuit protection (Ii ≈ 10 × In), ensuring reliable coordination with downstream protection devices.

With a rated current of 32 A and a high breaking capacity of 55 kA at 415 V AC, it is suitable for industrial installations with high prospective fault levels, offering strong short-circuit interruption capability and dependable feeder protection.
