Product Description

🔹 SENTRON 3WT Air Circuit Breaker with Microprocessor Trip Unit – 3WT8326-6UP16-5AB2

🔹 Product Description

The Siemens 3WT8326-6UP16-5AB2 is a high-capacity SENTRON 3WT series Air Circuit Breaker (ACB) designed for advanced low-voltage power distribution in heavy industrial and commercial electrical systems. It is equipped with a modern microprocessor-based electronic trip unit (ETU37WT class) that ensures precise, reliable, and intelligent protection of electrical networks.

This model is widely used in power plants, large industrial facilities, infrastructure projects, data centers, and commercial complexes, where high fault levels, system reliability, and selective coordination are essential for uninterrupted operation.

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

The 3WT8326 frame series (~3200A 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 system configuration and installation conditions).

This variant comes with a withdrawable (draw-out) design, enabling safe maintenance, easy replacement, and reduced downtime in modern switchgear systems such as MCC, PCC, and main LT panels.
