Residual Current Operated Circuit Breaker (RCCB) Leakage Protection System is Mainly Divided into Two Types: Primary and Secondary
Primary Leakage Protection System
● Application Scenario:
The primary leakage protection system is suitable for places with high requirements for personal safety, such as residences, hospitals, and schools. These locations typically involve frequent interactions with power supplies, necessitating higher levels of electrical safety protection.
● Sensitivity:
The primary leakage protection system exhibits high sensitivity and can detect minute leakage currents. Its setting value is usually below 10mA, meaning that once the circuit's leakage current surpasses this threshold, the system promptly cuts off the power supply.
● Function:
The primary leakage protection system's primary function is to promptly and effectively safeguard individuals from hazards like electric shocks. It swiftly identifies and mitigates potential electric shock risks, effectively safeguarding lives.
Secondary Leakage Protection System
● Application Scenario:
The secondary leakage protection system is suitable for places with lower demands for personal safety, such as factories, offices, and commercial buildings. While these environments pose lower risks, they still require a certain level of circuit protection.
● Sensitivity:
In contrast to the primary system, the secondary leakage protection system features lower sensitivity. Its setting value generally exceeds 30mA, allowing it to tolerate smaller leakage currents and disconnecting the power supply when significant leakage occurs.
● Function:
The secondary leakage protection system offers a degree of circuit protection, although additional safety measures may be necessary in high-risk settings. It functions to cut off the power supply upon detecting serious leakage to prevent incidents such as equipment damage and fires.
