Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1225-5EF32-0AA0
The Siemens 3VA1225-5EF32-0AA0 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, infrastructure projects, OEM power systems, and
commercial electrical installations where reliable fault protection and
operational safety are essential.
This MCCB is equipped with a thermal magnetic trip unit
(TM240 / 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 4-pole configuration,
making it suitable for applications requiring phase and neutral protection.
With a rated current of 250A and a breaking
capacity of 55kA at 415V AC, this MCCB is ideal for demanding industrial
and commercial power distribution systems with high fault-level requirements.
