Siemens SENTRON ACB – Microprocessor Based Trip Unit –
3WA1116-2AF32-0AA0
The Siemens 3WA1116-2AF32-0AA0 is a SENTRON 3WA
series Air Circuit Breaker (ACB) designed for advanced protection and
switching of low-voltage power distribution systems in industrial,
commercial, and infrastructure applications. It is widely used in main LT
panels, PCC systems, generator synchronization panels, data centers, and
process industries where high operational reliability and intelligent
protection are essential.
This ACB is equipped with a microprocessor-based
electronic trip unit that delivers precise protection against overload,
short-circuit, and fault conditions. The intelligent trip system supports
enhanced protection coordination, monitoring, diagnostics, and improved
operational safety in modern electrical distribution networks.
The SENTRON 3WA platform combines compact modular
construction with advanced digital functionality, making it suitable for smart
power distribution systems and critical electrical applications.
