🔹 Siemens SENTRON 3WT Air Circuit Breaker – 3WT8165-6KN24-5AB2 (Microprocessor Trip Unit ACB)
🔹 Product Description
The Siemens 3WT8165-6KN24-5AB2 is a SENTRON 3WT series Air Circuit Breaker (ACB) designed for high-performance low-voltage power distribution systems with advanced digital protection capabilities. It is equipped with a microprocessor-based electronic trip unit (ETU) that ensures precise, intelligent, and reliable protection for modern electrical networks.
This breaker is widely used in industrial plants, commercial buildings, infrastructure projects, data centers, and critical power distribution systems, where safe and uninterrupted power supply is essential.
The integrated microprocessor trip unit provides protection against overload, short circuit, and earth fault conditions, along with adjustable protection settings, fault diagnostics, and system coordination features. This improves overall electrical system stability and reduces downtime in complex distribution networks.
The SENTRON 3WT series is Siemens’ intelligent ACB platform designed for smart and modular power distribution systems. It supports withdrawable (draw-out) construction, allowing safe maintenance and easy replacement without shutting down the full system.
Based on Siemens 3WT architecture, the platform supports high-rated current frames (up to 4000A depending on variant) with strong breaking capacity up to ~80kA, making it suitable for demanding industrial applications.
