Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1450-5EE32-0AA0
The Siemens 3VA1450-5EE32-0AA0 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 current capacity and strong fault
interruption performance are required.
This model belongs to the 3VA14 frame series (up to 630A
class) and features a thermal magnetic trip unit (TM220 / ATFM type)
providing adjustable overload protection and fixed magnetic short-circuit
protection, ensuring safe and stable operation in electrical networks.
It is a 500A, 3-pole MCCB with a high breaking capacity
of 55kA at 415V AC, making it suitable for medium to heavy-duty
industrial feeder and incomer applications.
