Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1463-5EE32-0AA0
The Siemens 3VA1463-5EE32-0AA0 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 widely used in industrial switchboards,
PCC/MCC panels, feeder circuits, OEM machinery, and infrastructure power
distribution systems where high current capacity and strong fault
interruption performance are required.
This model belongs to the 3VA14 frame (630A class)
and features a thermal magnetic trip unit (TM220 / ATFM type), providing
adjustable overload protection and fixed instantaneous short-circuit
protection. This ensures stable coordination, selective tripping, and
safe operation under fault conditions in industrial networks.
It is a 3-pole MCCB with 630A rated current and 55kA
breaking capacity at 415V AC, making it suitable for heavy-duty feeder
and incomer applications in LT systems with high prospective fault levels.
