Siemens SENTRON ACB – Microprocessor Based Trip Unit –
3WA1112-2AF42-8EQ3-Z
The Siemens 3WA1112-2AF42-8EQ3-Z is a SENTRON 3WA
series Air Circuit Breaker (ACB) designed for advanced protection,
monitoring, and switching of low-voltage power distribution systems. It
is widely used in main LT panels, PCC systems, industrial plants, commercial
buildings, infrastructure facilities, and critical power applications where
high reliability and intelligent protection are required.
This ACB is equipped with a microprocessor-based
electronic trip unit, offering precise protection against overload,
short-circuit, earth fault, and abnormal operating conditions. The
intelligent trip system enables enhanced protection coordination, real-time
monitoring, diagnostics, and communication integration for modern smart power
distribution networks.
The 3WA series is designed with a compact modular
architecture that supports dependable switching performance, digital
connectivity, and efficient energy management in industrial and commercial
electrical installations.
