ACB: SENTRON 3WTPlus Microprocessor based trip unit – 3WT8101-6UA34-5AB2

Product Description

ACB: SENTRON 3WTPlus Microprocessor Based Trip Unit – 3WT8101-6UA34-5AB2

The Siemens 3WT8101-6UA34-5AB2 is an advanced microprocessor-based trip unit system used in the SENTRON 3WTPlus Air Circuit Breaker (ACB) platform. It is designed for intelligent protection, monitoring, and control of low-voltage power distribution systems, ensuring high reliability in critical electrical networks.

This configuration is typically used in draw-out (withdrawable) ACB systems with a 1000 A class rating and high short-circuit breaking capacity (up to 66 kA at 500 V AC), making it suitable for heavy-duty industrial applications.

The system provides advanced protection functions such as overload, short-circuit, and earth fault protection, along with adjustable electronic settings, real-time diagnostics, event logging, and communication-ready capability, enabling smart energy distribution and improved operational safety in modern switchgear systems.

It is widely used in main LT panels, industrial plants, commercial buildings, infrastructure projects, and data centers, where uninterrupted and safe power distribution is essential.
