🔹 Siemens SENTRON 3WT Air Circuit Breaker – 3WT8161-6UA34-5AB2 (Microprocessor Trip Unit ACB)
🔹 Product Description
The Siemens 3WT8161-6UA34-5AB2 is a SENTRON 3WT series Air Circuit Breaker (ACB) designed for high-capacity low-voltage power distribution and advanced protection systems. It is equipped with a microprocessor-based electronic trip unit (ETU37WT class) that provides intelligent and precise protection for modern electrical networks.
This breaker is widely used in industrial plants, manufacturing units, commercial complexes, data centers, and critical infrastructure systems, where high reliability, selectivity, and fault isolation are essential.
The integrated microprocessor trip unit ensures protection against overload, short circuit, and earth fault conditions, while also offering adjustable settings, fault diagnostics, and coordination capability with upstream and downstream devices. This improves system stability and reduces downtime in complex electrical networks.
The SENTRON 3WT series is Siemens’ advanced ACB platform designed for smart and modular power distribution systems. It supports withdrawable (draw-out) construction, making maintenance safer and faster without shutting down the entire system.
According to Siemens SENTRON 3WT technical specifications, this model belongs to the 1600A frame class with high breaking capacity (around 66kA at 500V AC), suitable for demanding industrial applications.
