Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1220-5GE42-0AA0
The Siemens 3VA1220-5GE42-0AA0 is a SENTRON 3VA1
series molded case circuit breaker (MCCB) designed for dependable
protection of low-voltage electrical distribution systems against overload
and short-circuit faults. It is widely used in industrial switchboards,
MCC/PCC panels, infrastructure projects, and commercial electrical distribution
systems where high fault interruption capability and reliable operation are
required.
This model is equipped with a thermal magnetic trip unit
(TM250 / ATFM – Adjustable Thermal Fixed Magnetic) that provides adjustable
overload protection and fixed instantaneous short-circuit protection. The
breaker belongs to the 3VA12 frame series and features a 4-pole
configuration, making it suitable for applications requiring phase and
neutral protection. (rs-online.com)
With a rated current of 200A and a breaking
capacity of 55kA at 415V AC, this MCCB is suitable for demanding industrial
and commercial distribution applications with high prospective fault levels.
