Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1220-5MH32-0AA0
The Siemens 3VA1220-5MH32-0AA0 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. It is commonly used in industrial switchboards,
PCC/MCC panels, infrastructure projects, and commercial power distribution
systems where dependable fault protection and high interruption capability
are required.
This MCCB is equipped with a thermal magnetic trip unit
(TM240 / ATFM – Adjustable Thermal Fixed Magnetic) that provides adjustable
overload protection and fixed magnetic short-circuit protection. The breaker
belongs to the 3VA12 frame series and features a 3-pole configuration,
making it suitable for three-phase feeder and incomer applications.
With a rated current of 200A and a high breaking
capacity, the breaker ensures safe interruption of fault currents in
demanding industrial environments while supporting efficient power distribution
and protection coordination.
