Product Description

Residual current device sensor (RCDs) or residual current sensors are indispensable safety components used to protect against electrical and ground faults in a variety of applications. Their high sensitivity, fast tripping mechanisms and compatibility with a variety of electrical systems make them vital for ensuring electrical safety in residential and industrial environments and preventing accidents and damage.

Standards and Regulations:
Residual current device sensor are subject to various national and international standards and regulations that define their installation requirements and performance standards. HYCA-F03 complies with IEC62752, IEC62955, UL2231 standards.

🛡️ Safety First

Designed to prevent electric shock, electrical fire, and equipment damage by monitoring current imbalances.

⚡ Rapid Tripping

Interruption occurs within milliseconds when a ground fault or leakage is detected to prevent accidents.

🔍 High Sensitivity

Able to detect small current imbalances in the milliamp (mA) range, ensuring early detection of faults.

⚙️ Self-testing

Includes mechanisms to ensure continued functionality through periodic automated tests.

Typical Applications

Electric Vehicle (EV) Charging: Prevents ground faults and leakage hazards in residential and public stations.
