SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1112-5EE32-0AA0

Product Description

Siemens SENTRON 3VM1112-5ED32-0AA0 – Thermal Magnetic Trip Unit MCCB

The Siemens 3VM1112-5ED32-0AA0 is a SENTRON 3VM molded case circuit breaker (MCCB) designed for dependable protection of low-voltage power distribution systems against overload and short-circuit faults. It is widely used in industrial switchboards, MCC panels, and feeder distribution systems where reliable fault protection and stable operation are required.

This model belongs to the 3VM1 IEC frame 160 series and comes with a fixed thermal–fixed magnetic (FTFM) trip unit, meaning the protection settings are factory-set for consistent performance and maintenance-free operation. It is designed for applications where no field adjustment is required and standard protection coordination is sufficient.

The breaker offers a rated current of 125 A and provides strong short-circuit protection suitable for industrial distribution networks. It is commonly used in feeder circuits, OEM panels, HVAC systems, and general industrial power systems.
