Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1332-5MH32-0AA0
The Siemens 3VA1332-5MH32-0AA0 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, and infrastructure electrical systems where
high fault level capacity and dependable switching performance are required.
This MCCB belongs to the 3VA13 frame series and is
equipped with a thermal magnetic trip unit (TM120M – Magnetic adjustable /
motor starter protection type), primarily optimized for short-circuit
protection applications, especially in motor starter and feeder circuits
where controlled magnetic protection is required.
With a rated current of 320A and a breaking
capacity of 55kA at 415V AC, this device is suitable for medium to
heavy-duty industrial applications requiring strong fault interruption
capability and reliable system protection.
