Product Overview

YuanXing Electronics’ PCB-mount Zero Sequence Current Transformers are compact, surface-mount components designed for ground fault detection and residual current monitoring in electronic circuits. They offer excellent linearity and a high sensitivity to very low fault currents, filtering out normal load currents to accurately capture imbalance. The components are epoxy potted for durability, offering 2500V dielectric strength and 5000V impulse protection. With rated inputs up to 200A and RoHS compliance, they provide reliable performance in demanding industrial environments.
