Product Overview

YuanXing Electronics Zero Sequence Current Transformers deliver high-precision monitoring for leakage prevention, relay protection, and grounding systems. Featuring solid and split-core configurations for cables and busbars (ZCTA, ZCTSA, ZCTB, ZCTSB series), they support inputs from 10mA to 20A. These transformers provide accuracy classes of 0.2 to 2.0 across a 50-2000 Hz frequency bandwidth. With 2500V AC dielectric strength and 5000V impulse protection, they ensure safety in harsh conditions. Operational from -20°C to +50°C and RoHS compliant, they are essential for manufacturers requiring reliable electronic components.
