SENTRON 3VM, Thermal Magnetic Trip Unit - 3VM1463-5GD42-0AA0

Product Description

Siemens SENTRON 3VM MCCB with Thermal Magnetic Trip Unit – 3VM1463-5GD42-0AA0

The Siemens 3VM1463-5GD42-0AA0 is a high-capacity Molded Case Circuit Breaker (MCCB) from the SENTRON 3VM1 series, designed for reliable protection of low-voltage electrical distribution systems against overload and short-circuit faults. This 4-pole MCCB comes with a Thermal Magnetic Trip Unit (TM210 / FTFM type), making it suitable for heavy-duty industrial power distribution, feeder protection, and main incomer applications.

It is commonly used in LT panels, MCC/PCC systems, industrial substations, and large electrical distribution boards, where high breaking capacity and robust performance are required.
