🔹 Siemens SENTRON 3WT Air Circuit Breaker – 3WT8165-6TP24-5AB2 (Microprocessor Trip Unit ACB)
🔹 Product Description
The Siemens 3WT8165-6TP24-5AB2 is a SENTRON 3WT series Air Circuit Breaker (ACB) designed for high-performance low-voltage power distribution systems with intelligent electronic protection. It is equipped with a microprocessor-based electronic trip unit (ETU) that ensures accurate, reliable, and adaptive protection for modern electrical networks.
This breaker is widely used in industrial plants, commercial complexes, data centers, infrastructure projects, and critical power distribution systems, where uninterrupted supply and high fault protection are essential.
The integrated microprocessor trip unit provides protection against overload, short circuit, and earth fault conditions, along with adjustable settings, diagnostic functions, and coordination capability. This helps improve system reliability, reduce downtime, and ensure selective tripping in complex electrical networks.
The SENTRON 3WT series is Siemens’ advanced ACB platform designed for smart and modular power distribution systems. It supports withdrawable (draw-out) construction, allowing safe maintenance and replacement without shutting down the entire system.
According to Siemens SENTRON 3WT design architecture, the series supports high-rated current frames up to 4000A with strong breaking capacity (up to ~85kA depending on configuration), making it suitable for heavy-duty industrial applications.
