Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1225-4EE32-0AA0
The Siemens 3VA1225-4EE32-0AA0 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
panels, MCC systems, infrastructure projects, and commercial electrical
installations where dependable circuit protection and operational safety
are required.
This MCCB is equipped with a thermal magnetic trip unit
(TM220 / ATFM – Adjustable Thermal Fixed Magnetic) that provides adjustable
overload protection and fixed magnetic short-circuit protection. The breaker
belongs to the 3VA12 frame series and features a 3-pole configuration,
making it suitable for three-phase feeder and incomer applications.
With a rated current of 250A and a breaking
capacity of 36kA at 415V AC, this breaker is suitable for medium-to-heavy
industrial distribution systems requiring reliable fault interruption
performance.
