Description
High-Sensitivity Leakage Detection
This is the Current Operated Residual Circuit Breaker. It uses a high-sensitivity zero-sequence current transformer. This product can detect very small leakage signals. It triggers the trip mechanism within the set threshold. The action time is ≤0.1s at IΔn. This fast response protects people from electric shock. Our factory has earned several national patents for this product. We work with research institutes to improve our technology.
Precision Manufacturing for Reliable Action
The core part of this Current Operated Residual Circuit Breaker is the zero-sequence current transformer. We control the winding process and magnetic core material strictly. Each batch goes through temperature rise tests. We also test action characteristics and dielectric strength. These tests ensure accurate and reliable operation. Our product has a residual current range of 0.5IΔn to 1IΔn. This gives you precise protection for your specific needs.
