H921-S6 Current Transducer Installation Guide

This document provides specifications, installation instructions, and wiring examples for the Schneider Electric H921-S6 current transducer, which senses AC current in three selectable ranges (0-30, 0-60, or 0-120 A) and outputs a 4-20 mA signal for building controllers. It also covers safety warnings, scaling, troubleshooting, and techniques for low or high current applications using wrapping or external current transformers.
