EKRCMU-1 is a residual current sensor with a highly integrated modular design, combining Type A RCD functionality with 6mA DC leakage detection, specially developed for charging pile leakage detection, Compliant with IEC 62955.

Its main function is to respond quickly when the charging pile detects residual current during operation, effectively preventing potential safety hazards caused by leakage, including but not limited to fire or electric shock accidents, thereby ensuring the safety and stability of the entire charging process, and is widely used in charging piles that meet mode 3 charging.
 

Key Features：

• Dual Protection: Integrates Type A RCD functionality with 6mA DC leakage detection in a single unit.

• IEC 62955 Compliance: Meets the requirements of IEC 62955, the international standard for RCMUs in EV charging stations.

• Enhanced DC Protection: Detects DC leakage currents as low as 6mA, crucial for modern EV charging safety.

• Connection Types: Suitable for both three-phase and single-phase connections.

• Fast Response Time: Interrupting Time according to IEC62752: 5.3.11 Table 2 and 3

• Self-Monitoring: Continuous self-test functionality ensures reliable operation.

• Compact Design: Engineered to be compact for easy integration into EV charging stations.
   

Applications:

• Mode 2 or Mode 3 AC charging stations

• Combined AC/DC charging points

• Home and workplace EV chargers

• Public charging infrastructure
