Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1225-5EE32-0AA0
The Siemens 3VA1225-5EE32-0AA0 is a SENTRON 3VA1
series molded case circuit breaker (MCCB) designed for dependable
protection of low-voltage electrical distribution systems against
overload and short-circuit faults. It is widely used in industrial
switchboards, PCC/MCC panels, commercial electrical installations,
infrastructure projects, and OEM power distribution systems where reliable
protection and high operational safety are required.
This MCCB features a thermal magnetic trip unit (TM240 /
ATFM – Adjustable Thermal Fixed Magnetic) that provides adjustable overload
protection along with fixed magnetic short-circuit protection for improved
protection coordination and system reliability. The breaker belongs to the 3VA12
frame series and is designed with a 3-pole configuration for
three-phase power distribution applications.
With a rated current of 250A and a breaking
capacity of 55kA at 415V AC, this MCCB is suitable for demanding industrial
applications with higher fault-level requirements.
