Product Description

🔹 SENTRON 3WT Air Circuit Breaker with Microprocessor Trip Unit – 3WT8206-6UN34-5AB2

🔹 Product Description

The Siemens 3WT8206-6UN34-5AB2 is a high-performance SENTRON 3WT series Air Circuit Breaker (ACB) designed for reliable low-voltage power distribution in demanding industrial and commercial applications. It comes equipped with an advanced microprocessor-based electronic trip unit (ETU37WT class) that ensures precise protection, monitoring, and control of electrical networks.

This model 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 essential for uninterrupted operations.

The breaker provides complete protection against overload, short circuit, and earth fault conditions, ensuring safe isolation of faulty sections and improving overall system stability and uptime.

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

This variant features a withdrawable (draw-out) design, allowing easy maintenance, safe replacement, and reduced downtime in modern modular switchgear systems.
