Product Description

🔹 SENTRON 3WT Air Circuit Breaker with Microprocessor Trip Unit – 3WT8206-6UA38-5AB2

🔹 Product Description

The Siemens 3WT8206-6UA38-5AB2 is a high-performance SENTRON 3WT series Air Circuit Breaker (ACB) designed for reliable low-voltage power distribution in demanding industrial and commercial environments. It is equipped with an advanced microprocessor-based electronic trip unit (ETU37WT class) that ensures precise protection, monitoring, and control of electrical networks.

This ACB is widely used in industrial plants, commercial complexes, data centers, hospitals, and main LT switchgear systems, where system reliability, fault protection, and selective coordination are critical.

The device provides protection against overload, short circuit, and earth fault conditions, ensuring safe isolation of faulty circuits and minimizing downtime in electrical distribution systems.

The 3WT8206 frame series (~2000A class, Size II) is engineered for heavy-duty applications and typically supports high breaking capacity up to approximately 66 kA at 500V AC (depending on configuration).

This variant comes in a withdrawable (draw-out) design, allowing safe maintenance and easy replacement without shutting down the entire system, making it ideal for modern modular switchgear systems.
