Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1332-5EF32-0AA0
The Siemens 3VA1332-5EF32-0AA0 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/MCC panels, OEM machinery, infrastructure projects, and commercial power
systems where high fault-level protection and stable switching performance
are required.
This MCCB belongs to the 3VA13 frame series and is
equipped with a thermal magnetic trip unit (TM240 / ATAM – Adjustable
Thermal Adjustable Magnetic), providing adjustable overload protection
(Ir 224–320 A) and adjustable short-circuit protection (Ii 5–10 × In)
for precise system coordination and safety.
With a rated current of 320A and a breaking
capacity of 55kA at 415V AC, this breaker is suitable for heavy-duty
industrial applications requiring strong fault interruption capability and
reliable performance in demanding electrical networks.
