Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1332-5EE32-0AA0
The Siemens 3VA1332-5EE32-0AA0 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 systems where high fault level protection and dependable
switching performance are required.
This MCCB belongs to the 3VA13 frame series and
features a thermal magnetic trip unit (TM220 / ATFM – Adjustable Thermal
Fixed Magnetic), providing adjustable overload protection along with
fixed magnetic short-circuit protection for stable coordination and safe
operation in electrical networks.
With a rated current of 320A and a breaking
capacity of 55kA at 415V AC, this device is suitable for heavy-duty industrial
power distribution applications requiring strong fault interruption
capability and high reliability.
