SENTRON 3VA MCCB, Thermal Magnetic Trip Unit - 3VA1220-5EE32-0AA0

Product Description

Siemens SENTRON 3VA MCCB, Thermal Magnetic Trip Unit – 3VA1220-5EE32-0AA0

The Siemens 3VA1220-5EE32-0AA0 is a SENTRON 3VA1 series Molded Case Circuit Breaker (MCCB) designed for reliable protection of low-voltage electrical distribution systems against overload and short-circuit faults. This 3-pole MCCB belongs to the 3VA12 frame size (up to 250A class) and is widely used in industrial feeder, MCC, and power distribution applications where high breaking capacity and stable performance are required.

It uses a Thermal Magnetic Trip Unit (TM / ATFM type) to ensure both long-time overload protection and instantaneous short-circuit protection.
