Product Description

🔹 SENTRON 3WT Air Circuit Breaker with Microprocessor Trip Unit – 3WT8206-6UM34-5AB2

🔹 Product Description

The Siemens 3WT8206-6UM34-5AB2 is a high-performance SENTRON 3WT series Air Circuit Breaker (ACB) designed for reliable low-voltage power distribution in heavy-duty industrial and commercial applications. It features an advanced microprocessor-based electronic trip unit (ETU37WT class) that ensures accurate protection, monitoring, and control of electrical systems.

This model is widely used in industrial plants, commercial buildings, data centers, hospitals, and main LT switchgear systems, where high system reliability, fault protection, and selective coordination are essential.

The breaker provides protection against overload, short circuit, and earth fault conditions, ensuring safe isolation of faulty circuits and improved system stability.

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

This variant is designed with a withdrawable (draw-out) mechanism, allowing safe maintenance, easy replacement, and minimal downtime in complex electrical distribution systems.
