Residual Current Circuit Breaker
Residual current circuit breakers not only accurately detect residual current in a circuit (such as leakage current caused by human electric shock or insulation damage) and quickly disconnect the circuit to prevent electric shock injuries, but they also simultaneously respond to circuit overloads by rapidly disconnecting when the current exceeds the rated range, preventing overheating, equipment damage, or fire. This single device provides dual critical protection, creating a double safety barrier for power distribution systems. They adhere to stringent high-reliability standards and adhere to the international IEC 61008 standard during their development and production.

Features of Residual current circuit breaker
Residual current circuit breakers (RCCBs) accurately monitor residual current in electrical circuits, tripping and interrupting the circuit within milliseconds to effectively prevent electric shock and electrical fire hazards. Widely used in residential, commercial, and industrial settings for circuit isolation and leakage protection ·Global Market Adaptability: Supports OEM/ODM services and exports to regions like South America, South Asia, and the Middle East
Specifications
The residual current circuit breaker mainly has the following functions:
| Function | Description |
| Protection Against Earth Faults | Detects and interrupts residual (leakage) currents to prevent electric shock and fires caused by earth faults. |
| Overcurrent Protection | Provides protection against overcurrent conditions, such as short circuits and overloads, by breaking the circuit. |
| Automatic Trip | Automatically trips when a predefined threshold of residual current is detected, ensuring immediate disconnection from the power source. |
| Manual Reset | Requires manual resetting after a trip, ensuring that the fault is addressed before re-energizing the circuit. |
| Multi-Pole Configuration | Available in multiple pole configurations (e.g., 1P+N, 2P) to cater to different circuit protection needs. |
| Sensitivity Levels | Offers various sensitivity levels (e.g., 30mA, 100mA, 300mA) to accommodate different applications and risk levels. |
| Compliance with Standards | Designed and tested according to international standards (e.g., IEC/EN 61009) to ensure reliability and safety. |
