Product Description

🔹 SENTRON 3WT Air Circuit Breaker with Microprocessor Trip Unit – 3WT8326-6UN34-5AB2

🔹 Product Description

The Siemens 3WT8326-6UN34-5AB2 is a high-capacity SENTRON 3WT series Air Circuit Breaker (ACB) designed for advanced low-voltage power distribution in demanding industrial and commercial environments. It is equipped with a microprocessor-based electronic trip unit (ETU37WT class) that ensures precise, reliable, and intelligent protection of electrical systems.

This model is widely used in large industrial plants, power distribution networks, commercial complexes, hospitals, and data centers, where high fault levels, system stability, and selective coordination are critical.

The breaker provides full protection against overload, short circuit, and earth fault conditions, ensuring safe isolation of faulty circuits and minimizing downtime in critical applications.

The 3WT8326 frame series (~3200A class, Size II) is designed for heavy-duty applications and typically supports a high breaking capacity of up to approximately 66 kA at 500V AC (depending on system configuration and trip unit setup).

This variant features a withdrawable (draw-out) design, allowing safe maintenance, quick replacement, and reduced downtime in modern modular switchgear systems, making it ideal for MCC, PCC, and main LT distribution panels.
