The ABB Residual Current Circuit Breaker (RCCB) is an essential component for electrical circuit protection. It is designed to detect and provide protection against residual currents, which are unwanted currents that can occur due to insulation faults or electrical leakage.
The RCCB operates on an AC type mechanism, meaning it is sensitive to alternating currents. It continuously monitors the current flowing in the circuit and compares it to the current returning from the circuit. If a residual current is detected that exceeds the predetermined threshold, typically set at 30 mA, the RCCB will trip and disconnect the power supply, preventing potential electrical hazards.
The ABB RCCB is a 2-pole device, meaning it can monitor and protect two live conductors simultaneously. This makes it suitable for applications where two-phase or split-phase circuits are present.
ABB is a trusted brand known for its high-quality electrical products. The RCCB is designed and manufactured to meet rigorous industry standards, ensuring reliable performance and protection.
The ABB RCCB with a sensitivity of 30 mA provides an effective solution for detecting and protecting against electrical faults and hazards. It is commonly used in residential, commercial, and industrial applications to enhance electrical safety.
