SENTRON 3VA MCCB, Thermal Magnetic Trip Unit - 3VA1132-5GE42-0AA0

Product Description

Siemens SENTRON 3VA MCCB, Thermal Magnetic Trip Unit – 3VA1132-5GE42-0AA0

The Siemens 3VA1132-5GE42-0AA0 is a SENTRON 3VA1 series Molded Case Circuit Breaker (MCCB) designed for reliable protection of low-voltage distribution systems against overload and short-circuit faults. This 4-pole MCCB is equipped with a Thermal Magnetic Trip Unit (TM220 / ATFM type), providing adjustable overload protection and fixed instantaneous short-circuit protection, making it suitable for demanding industrial and commercial applications.

It is widely used in LT panels, MCC/PCC systems, feeder circuits, and industrial distribution boards, especially where high breaking capacity and neutral protection are required.
