🔹 Siemens SENTRON 3WT Air Circuit Breaker – 3WT8202-6UA34-5AB2 (Microprocessor Trip Unit ACB)
🔹 Product Description
The Siemens 3WT8202-6UA34-5AB2 is a SENTRON 3WT series Air Circuit Breaker (ACB) designed for high-capacity low-voltage power distribution systems with intelligent electronic protection. It comes equipped with a microprocessor-based electronic trip unit (ETU37WT class) that ensures precise and reliable protection for modern electrical installations.
This breaker is widely used in industrial plants, commercial buildings, infrastructure projects, data centers, and main LT distribution systems, where high fault levels, system reliability, and selective coordination are critical.
The integrated electronic trip unit provides protection against overload, short circuit, and earth fault conditions, along with adjustable settings, fault diagnostics, and coordination functions. This helps improve system stability and reduces downtime in complex electrical networks.
The SENTRON 3WT series is Siemens’ advanced ACB platform designed for smart, modular, and withdrawable power distribution systems, allowing safe maintenance and easy replacement without shutting down the complete system.
Based on Siemens SENTRON 3WT technical architecture, the 3WT8202 frame class is typically rated at 2000A with a 3-pole configuration and breaking capacity up to around 66kA at 500V AC, depending on configuration and trip unit version.
