- Electrical leakage is unpredictable and impossible to eliminate — a silent killer that poses serious risks. Accidents caused by leakage are alarmingly common, often resulting in unnecessary loss of life. The Yu-Chen Electrical Leakage Protection System provides dual-layer protection for both personnel and equipment, effectively preventing electric shocks, fires, equipment damage, and costly production downtime caused by leakage.
- According to international regulations, the only proven device to effectively prevent the dangers of leakage is the Residual Current Device (RCD). However, when the RCD is triggered, power is immediately cut off — halting production lines and machinery, leading to significant economic loss.
Currently, there are no alternative solutions on the market that can offer continuous protection without interrupting power. Only the Yu-Chen Electrical Leakage Protection System is capable of shielding personnel from electric shock risks within regulated system parameters, while preventing RCD tripping — ensuring uninterrupted power and minimizing costly production disruptions.

It is designed to effectively prevent electric leakage and electric shock, providing enhanced protection for both personnel and electrical equipment.

Four Core Functions of the Yu-Chen Electrical Leakage Protection System
1. Energy Efficiency
- Absorbs leakage current and redirects it back to the original load loop, reducing power loss and achieving energy-saving performance. Fully compliant with ESG energy efficiency standards.
2. Safety Assurance
- Addresses grounding deficiencies by absorbing leakage current, reducing the risk of electric shock and ensuring both personnel safety and the stable operation of equipment.
3. Production Line & Equipment Protection
- Prevents RCD tripping caused by leakage current, avoiding production downtime and equipment failure.
- Mitigates risks of electrical fires and provides surge protection (internal equipment protection).
- Stabilizes voltage and frequency, improving power quality issues such as three-phase imbalance.
4. Protection in Harsh Environments and Temporary Power Applications
- Maintains normal operation even when electrical equipment is exposed to flooding.
- Provides reliable leakage protection in outdoor environments and in locations with frequent circuit breaker tripping issues.
