🔹 Siemens SENTRON 3WT Air Circuit Breaker – 3WT8101-6KN24-5AB2 (Microprocessor Trip Unit ACB)
🔹 Product Description
The Siemens 3WT8101-6KN24-5AB2 is a SENTRON 3WT series Air Circuit Breaker (ACB) designed for advanced low-voltage power distribution and intelligent protection systems. It is equipped with a microprocessor-based electronic trip unit (ETU) that ensures precise and reliable protection for modern electrical installations.
This breaker is widely used in industrial plants, commercial buildings, data centers, infrastructure projects, and critical power distribution networks, where high reliability, selectivity, and system safety are required.
The integrated microprocessor trip unit provides protection against overload, short circuit, and earth fault conditions, while also enabling adjustable settings, fault diagnostics, and system monitoring capabilities. This allows better coordination with upstream and downstream protection devices, improving overall system stability.
The SENTRON 3WT series is Siemens’ intelligent ACB platform, designed for modern smart power distribution systems. It supports modular architecture, withdrawable execution, and optional communication integration, making it suitable for SCADA-based and energy-managed electrical networks.
According to Siemens 3WT system architecture, the series supports high-rated current frames up to several thousand amperes with strong breaking capacity and configurable protection functions, ensuring robust performance in demanding environments.
