Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1340-4GE42-0AA0
The Siemens 3VA1340-4GE42-0AA0 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 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 (TM220 / ATFM – Adjustable
Thermal Fixed Magnetic) providing adjustable overload protection (Ir
approx. 280–400 A) and fixed magnetic short-circuit protection (Ii
typically ~10 × In) for safe and coordinated operation in electrical
networks.
With a rated current of 400A and a breaking
capacity of 36kA at 415V AC, it is suitable for medium to heavy-duty
industrial applications requiring reliable fault interruption and stable
system performance.
