Siemens SENTRON 3VM MCCB – Thermal Magnetic Trip Unit – 3VM1132-4GD42-0AA0
The Siemens 3VM1132-4GD42-0AA0 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 networks where reliable and compact protection is 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 adjustable) and fixed instantaneous short-circuit protection, ensuring proper coordination with downstream devices.
With a rated current of 32 A and a breaking capacity of 36 kA at 415 V AC, it is suitable for industrial applications with higher fault levels, offering stronger short-circuit protection compared to standard 25 kA variants.
