Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1332-4GE42-0AA0
The Siemens 3VA1332-4GE42-0AA0 is a SENTRON 3VA1
series molded case circuit breaker (MCCB) designed for reliable protection
of low-voltage power distribution systems against overload and
short-circuit faults. It is widely used in industrial switchboards,
PCC/MCC panels, OEM machinery, infrastructure projects, and commercial
electrical installations where high fault-level performance and operational
safety are essential.
This MCCB belongs to the 3VA13 frame series and is
equipped with a thermal magnetic trip unit (TM220 / ATFM – Adjustable
Thermal Fixed Magnetic), providing adjustable overload protection
along with fixed magnetic short-circuit protection for improved
coordination and system reliability.
With a rated current of 320A and a breaking
capacity of 36kA at 415V AC, this MCCB is suitable for medium to
heavy-duty industrial power distribution applications requiring stable and
reliable fault interruption.
