Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1450-5MH32-0AA0
The Siemens 3VA1450-5MH32-0AA0 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, infrastructure projects, and commercial
installations where high current capacity, strong breaking performance,
and stable feeder protection are required.
This model belongs to the 3VA14 frame series (up to 630A
class) and is equipped with a thermal magnetic trip unit (TM120M /
starter protection type). It provides short-circuit protection with
fixed/adjustable instantaneous release, making it suitable for motor
starter protection and feeder applications where overload protection may be
handled externally or via coordination systems.
It offers a rated current of 500A with a high
breaking capacity of 55kA at 415V AC, ensuring reliable interruption under
heavy fault conditions in industrial networks.
