Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1450-4GE42-0AA0
The Siemens 3VA1450-4GE42-0AA0 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 current capacity and strong fault
interruption performance are required.
This model belongs to the 3VA14 frame series (up to 630A
class) and is equipped with a thermal magnetic trip unit (TM220 / ATFM
type) providing adjustable overload protection and fixed/standard
short-circuit protection, ensuring safe and stable operation in electrical
distribution networks.
It has a rated current of 500A and a breaking
capacity of 36kA at 415V AC, making it suitable for medium to heavy-duty
industrial applications where reliable fault interruption and system
protection are required.
