Siemens SENTRON 3VA MCCB, Thermal Magnetic Trip Unit –
3VA1580-5EF32-0AA0
The Siemens 3VA1580-5EF32-0AA0 is a SENTRON 3VA1
series Molded Case Circuit Breaker (MCCB) designed for high-capacity
low-voltage power distribution systems. It provides reliable protection against
overload and short-circuit faults in demanding industrial applications such
as main incomers, PCC/MCC panels, and heavy electrical distribution networks.
This model belongs to the 3VA15 / 3VA1 frame (up to 1000A
class) and uses a Thermal Magnetic Trip Unit (TM240 type) to ensure
stable protection performance.
