Siemens SENTRON ACB – Microprocessor Based Trip Unit –
3WA1116-2AF32-4EA4
The Siemens 3WA1116-2AF32-4EA4 is a SENTRON 3WA
series Air Circuit Breaker (ACB) engineered for advanced protection and
reliable switching in low-voltage power distribution systems. It is
widely used in main LT panels, PCC switchboards, industrial plants,
commercial buildings, utilities, and infrastructure projects where
intelligent protection and high operational reliability are essential.
This ACB features a microprocessor-based electronic trip
unit that provides accurate protection against overload, short-circuit,
and fault conditions. The intelligent trip system enables precise
protection coordination, system diagnostics, monitoring, and improved
operational safety for modern power distribution networks.
The SENTRON 3WA platform combines compact modular
construction with advanced digital capability, making it suitable for smart
power management and critical industrial electrical systems.
